Skip the dough and stuff all of your favorite pizza toppings into spaghetti squash boats for a fun and healthy dinner that'll please the whole family. We love the combination of mushrooms, bell peppers, pepperoni and mozzarella, but feel free to mix it up with your favorite pizza ingredients. You could throw in a bit of chopped cooked broccoli, for example, or add some olives or chopped artichoke hearts. And of course feel free to omit the pepperoni to make the dish vegetarian. Round out the meal with a simple salad.
