Vegetable and Cheese Tomato Lasagna

Finely dice the onion and sauté it in olive oil until soft.

Add the minced garlic, followed by the diced zucchini and bell pepper.

Cook for a few minutes, then stir in the chopped tomatoes and tomato sauce.

Season with salt and pepper, and simmer the vegetables until the sauce slightly thickens.

In a baking dish, spread a little sauce, then place a layer of lasagna sheets, some of the vegetable filling, and a bit of grated cheese.

Repeat the layers until all ingredients are used up, topping the final layer with cheese.
