Halve the zucchini, then cut into slices. Core the peppers, peel the onion and cut both into slices.
Put everything in a small ovenproof dish, season with salt and pepper and sprinkle with the sheep`s cheese cut into cubes. In the oven and bake at 200 ° C (top / bottom heat) for about 15 minutes.
My serving of vegetables is 145 g. If it`s more or less for you, just vary the amount of zucchini.
