Heat 1 tbsp of sunflower oil in a non-stick frying pan. Chop 1 small red onion, a handful of mushrooms, half a red and green pepper and 1 small courgette. Add all these ingredients to the pan and cook for 5 minutes, until they begin to soften. Slice 6 cooked new potatoes, add to the pan and cook for a further few minutes, being careful not to break up the slices. Beat 4 eggs and pour into the pan as well. Cook until the tortilla is almost set, then place under a hot grill until the egg on top is also set. Serve with salad and 1 slice of wholegrain bread per person. Finish with 1 bowl of fruit salad per person.
