The choice is yours entirely, whatever you put in your stuffed peppers will do the trick, or whatever you get on your regular pizza order. Sometimes I like to use prosciutto, bacon, and even use goat cheese on occasion For this particular pizza stuffed peppers recipe, though, let's go with Italian sausage, pepperoni, garlic, oregano, and mozzarella cheese. Alternatively, you could replace the Italian sausage with Turkey sausage instead. You can absolutely add about 1 cup of cooked quinoa to this recipe and spoon into large and cored bell peppers before baking.
