Pêches au Thon

  Required
• Tuna, light, canned in water 200g, drained

Execution Methodology & Culinary Technique

1. 1

   Drain the Peaches and Tuna

   5 Mins • Drain Cold, about 4°C (39°F)

   Open the can of peaches, drain off all the juice and set the 4 halves cut-side up on paper towels. Pat them dry inside and out. Drain the tuna in a sieve, pressing gently with a fork to squeeze out as much water as you can.

   Wet tuna is the most common fault here — press it firmly in the sieve, or the filling turns sloppy.

   Done when: The peach halves are dry to the touch and the tuna is flaky, not wet.

2. 2

   Mix the Tuna Filling

   5 Mins • Mix Cold, about 4°C (39°F)

   Put the drained tuna in a bowl and break it up with a fork. Add the mayonnaise, lemon juice, mustard, half the snipped chives, salt and pepper, and stir until the mixture is creamy but still has visible flakes of tuna. Taste and add a little more lemon or salt if needed.

   Stir, do not mash — the filling should be flaky and light, not a smooth paste.

   Done when: The filling is creamy, holds its shape on a spoon, and tastes bright and salty.

3. 3

   Fill the Peach Halves

   5 Mins • Fill Cold, about 4°C (39°F)

   Spoon a generous mound of the tuna mixture into the hollow of each peach half, piling it up a little above the rim. You should use all of the filling across the 4 halves.

   Fill the peaches just before serving so the juice does not soften the filling.

   Done when: Each peach half carries a neat, generous dome of tuna filling.

4. 4

   Plate and Garnish

   5 Mins • Plate Cold, about 4°C (39°F)

   Lay one lettuce leaf on each plate and set a filled peach half on it. Scatter the remaining chives over the tuna and place two cherry tomato halves beside each peach.

   The lettuce is not just decoration — it stops the peach sliding around the plate.

   Done when: Each plate holds one filled peach on lettuce, with chives and tomato beside it.

5. 5

   Serve Cold

   2 Mins • Serve Serve cold, about 4°C (39°F)

   Serve at once, cold from the fridge, with crusty bread on the side. If you made the filling ahead, keep the peaches and the filling separate and fill them at the last minute.

   Serve cold — warm peaches turn soft and the mayonnaise loosens.

   Done when: The peaches are cold, the filling is firm and creamy, and the plate looks fresh.

Who Should Eat It

Who Should Eat

• General adultsA light starter at 194 kcal per serving with 13.7 g of protein — a good light lunch when paired with bread and salad.
• ChildrenChildren often enjoy the sweet peach, but the tuna filling is salty and fishy, so offer a small taste first.
• ElderlySoft, cool and easy to chew, with good protein — a gentle light lunch, but watch the salt.
• Pregnant womenTuna provides protein and omega-3 during pregnancy, but keep to one serving and use light tuna, which is lower in mercury than white tuna; check with your clinician about fish intake.
• Breastfeeding womenA light, protein-rich lunch that provides energy without heaviness; keep to one serving because of the salt.
• AthletesHigh in protein and light in calories, so it works well as a light lunch around training; add bread for more carbohydrate.
• Weight gainLight and low in calories, so it will not add much on its own — add bread and a bigger salad to make it a fuller meal.
• Weight lossLow in calories and high in protein, so it fits a weight-loss lunch well — one serving with salad, and go easy on the bread.

Health Conditions — Adjust or Avoid

Conditions

• DiabetesLow in carbohydrate and sugar for a fruit dish, but the peaches are sweet, so people with diabetes should keep to one half and check with their clinician.
• High blood pressureCanned tuna and mayonnaise are salty at 389 mg of sodium per serving, so people with high blood pressure should keep to one serving and skip extra salt; check with your clinician.
• Kidney diseaseTuna is high in potassium and phosphorus, so people with kidney disease should eat this rarely and in a small portion; ask your clinician.
• GoutTuna is a fish, which is moderate in purines — people with gout should eat this only occasionally and in a small portion; ask your clinician.
• Stomach issuesCold, soft and easy to digest, so it is usually gentle on the stomach; eat slowly and stop if the mayonnaise feels heavy.
• Cardiovascular diseaseTuna brings omega-3 fats, but the mayonnaise adds saturated fat, so this is a light occasional lunch rather than a daily one for heart health; check with your clinician.
• Fatty liverA light, low-fat starter is gentle on the liver in small amounts — keep to one serving; ask your clinician for guidance.
• Food allergiesContains fish (tuna), egg (mayonnaise) and mustard. There is no milk, peanut, tree nut or wheat in this recipe. If you are allergic to fish, egg or mustard, do not eat this dish.
• Special therapeutic dietsNot suitable for low-sodium or low-fat therapeutic diets; a version with yoghurt instead of mayonnaise is lighter but will not taste the same. Ask your clinician or dietitian before changing your diet.

If you have a medical condition, consult your doctor before changing your diet.

kitchen Storage & Use

Storage & Use

How to store

Cover tightly with cling film and keep in the fridge; store the filling and the peach halves separately if possible.

In the fridge

1 day in the fridge; the filled peaches soften and weep juice after that.

In the freezer

Not suitable — mayonnaise splits and peaches turn mushy when thawed.

How to reheat

Do not reheat — serve cold. If chilled, serve straight from the fridge at about 4°C (39°F).

Freezing recommended

No — make it fresh and eat it the same day.

Signs it has spoiled

Sour or fishy smell stronger than fresh tuna, slimy texture, or discoloured peach flesh.
