Wash mint, dab dry, pluck leaves from the stalks and chop finely. Knead mint and butter, season with salt, pepper and sugar. Clean, wash and drain the salad and cut into wide strips.
Peel the shallots and cut into strips. Wash the meat and dab dry. Heat 1 tablespoon of oil in a frying pan. Fry the fillets medium rare for 6-8 minutes while turning. Steam peas in a pot covered with a little water for 2-3 minutes until defrosted.
Add 4 tablespoons of olive oil and shallots, steam for 3-4 minutes while turning, remove from heat and fold in salad. Season to taste with salt, pepper and sugar. Slice parmesan. Season meat with salt and pepper, remove from the pan, cut into slices and arrange on plates with peas and shallots vegetables.
Spread butter on the meat pieces and sprinkle everything with parmesan. Baguette tastes good with it.
