Clean, wash and cut the salad into strips. Grease an ovenproof dish. Mix tomato paste and cream, season with salt and pepper and stir into the ravioli. Put half of the ravioli into the dish, spread the lettuce and peas on top.
Add the rest of the ravioli and bake in a preheated oven (electric: 200 ° C / gas: level 3) for about 20 minutes. Grate the cheese and bake about 5 minutes before the end of the cooking time.
