When I make the creamy garlic alfredo I always freeze a portion of it so I can use it later for pizzas. First follow the recipe for grilled pizza crusts, then pick out your favorite(s) kind of sauce(s). Then prep all of your toppings. Slap them all together, put the pizza on the grill to get it warm and melty and you've got a delicious meal! Here are a list of toppings and pizzas we make/use at our house.
These are our favorite combos:
Grilled Chicken Pesto Pizza
store bought pesto (sometimes I mix it with the alfredo to make it creamy)
