Preheat the oven to 450 degrees. To make the filling, heat 2 tablespoons of the olive oil in a frying pan and saute the garlic and onion until transparent, not brown. Remove and set aside. Add the remaining 2 tablespoons olive oil and saute the garlic and onion until transparent, not brown. Remove and set aside. Add the remaining 2 tablespoons olive oil and saute the zucchini and green pepper until slightly tender. Combine them with the onion mixture. In a separate bowl, mix the eggs with the cottage cheese. Stir in the cream cheese and, if necessary, slice with a pastry cutter to break up any lumps. Add the salt, pepper, dill, and nutmeg. Then add the onion mixture, spinach, Parmesan cheese, and cream. Mix well. Pour into the crust. Bake for 40 minutes, or until the center is set. Remove the sides from the quiche pan and serve hot.
