Chop the onions and garlic and sauté them with the chopped Swiss chard (stems and leaves) in a little oil. At the same time, simmer the tomatoes, season with salt and pepper, season with chilli as required. Layer alternately in an ovenproof dish: Swiss chard, lasagne leaves and diced mozzarella, tomato sauce and fresh basil leaves, grated Parmesan. Finish with a layer of diced mozzarella, mixed with parmesan and breadcrumbs.
Bake the casserole in the oven for about 45 minutes at 180 degrees.
The lasagne sheets must be soft, the cheese / bread mixture must be baked until crispy and brown.
The dish is ideal for using leftovers from red pasta sauces, such as: Bolognese sauce or tuna tomato sauce or just plain tomato sauce. We think the combination of chard and tomato is simply brilliant.
