My kids are eating this as we speak and I couldn't believe how great it turned out! Here is what we had:
Leftovers: 1 small tub garlic butter from last night's pizza, tiny bit cheapie Parmesan, 3/4 cup colby jack cheese
Here's what we did:
Make a half batch of pizza crust (enough for 1/2 pizza). Grease a round cake pan. Smoosh pizza crust down and top with garlic butter. Sprinkle with a small handful of Parmesan and 1/2-3/4 cup other cheese. Sprinkle with a bit of dried basil and parsley.
Bake in a preheated oven at 425 degrees for 17-18 minutes. Pop it out onto a cutting board and cut into wedges. We had ours with Ranch dressing, but it'd be a great side for spaghetti or even as an appetizer with pizza sauce.
You could whip up your own garlic butter to produce the same results...butter, garlic powder, salt. Let me know if you have any additional suggestions!
