When you're lacking inspiration for pizza toppings or your cupboards are practically bare, take some ground beef and brown it in a skillet with whatever other chopped veggies you have on hand. Spread the mixture on a prepared pizza crust with grated or fresh Mozzarella cheese before popping it in the oven for a fast fix. Easy homemade pizza like this always tastes better than the store-bought kind (and it's much healthier!).
