Two jacket potatoes with tuna mayonnaise, each with lettuce and sliced tomato

Makes 2 servings · About 25 minutes

Ingredients

  • 600g baking potatoes, skin on
  • 200g tuna in spring water, drained
  • 30g light mayonnaise
  • 100g lettuce
  • 160g tomato

Equipment

  • microwave
  • microwave-safe plate
  • fork
  • oven gloves
  • knife
  • chopping board
  • bowl
  • spoon
  • can opener if needed
  • kitchen scales

Method

  1. Use two potatoes about 300g each. Scrub and prick them all over. Put on a microwave-safe plate and follow your appliance guide; at 800W allow about 12–16 minutes for two, turning halfway, then continue in 1-minute bursts until completely soft. Stand for 2 minutes. Appliances and potato size vary; the centre must be tender.
  2. Drain and weigh the tinned tuna, flake it and mix with the mayonnaise. Keep chilled until the potatoes are ready.
  3. Wash and dry the lettuce and tomato and divide between two plates. Split and fluff each potato, add half the topping to each and serve the salad alongside. Eat immediately. For an oven-only option, allow 60–90 minutes plus preheating; this is a separate longer choice.
