Heat the grill to its highest setting. Crack the eggs into a large bowl, whisk in the milk, then combine with half the cheese, the mint, cooked pasta shells and peas, and add a big pinch of seasoning. Melt the butter in a medium ovenproof non-stick frying pan over a medium heat. Tip in the pasta and egg mixture and leave to set for about 5 mins.

Scatter the remaining parmesan on top and put under the grill for 10 mins until cooked through, then slide onto a plate. Cut into slices and serve with a green salad.
