Grate the Parmesan finely - or rely on ready-to-use grated Parmesan from your trusted food store.
Grate the Emmental cheese roughly - or rely on ready-to-use grated Emmental cheese also from your trusted food store.
Put a splash of olive oil in a frying pan.
Mix the minced meat with the rest of ingredients and knead carefully – with your hands. Form small balls (3 – 4 cm). Fry the meat balls until brown – they need not roasted thoroughly. Set aside
Clean and trim the vegetables. Cut the courgette into thick disks, the peppers in long strips and the onion in thick slices. Set aside.
Mix the ingredients for the sauce and cut the canned tomatoes into smaller pieces. Pour the sauce in the casserole and add the vegetables. Also add the meatballs.
Sprinkle the grated Emmental cheese all over the mess – it’ll get crispy!
Put it in the oven for about 40 min at 160° C fan. If the vegetables seem not soft enough at the end … just add another 5 or 10 min.
Serve at once.
