Cut the zucchini lengthways and hollow out, cut the pulp into small pieces and place in a large bowl. Core the peppers, cut into small pieces and add to the zucchini. Finely chop parsley and garlic and add to the bowl as well. Put the quark in the bowl, mix well with the remaining ingredients and season the mixture with paprika powder, salt and pepper.
Preheat the oven to top / bottom heat 180 degrees.
Pour some water into a baking dish and place the zucchini halves in it. Spread the quark mixture in the zucchini halves. Rub the parmesan cheese over the zucchini if you like.
