Method: Cut zucchini clean inside with a spoon and put salt in small amount. Boil pasta / rice and place a layer in zucchini. Chopped onion, peppers and tomatoes, then place them over pasta / rice. Sprinkle parmesan and chopped parsley.
I think I remember hearing this trick: to draw the moisture from the zucchini before cooking, sprinkle a bit of salt on the cut vegetable, and rest. Then blot the moisture with paper towel before fixing recipe. Need: bread crumbs, eggs
