I have a confession to make: I'm addicted to California Pizza Kitchen frozen margherita pizzas. Like, I can eat the whole thing myself. And I do. But with my mission to eat healthier, I've put a stop to that pizza binge. I knew I'd have California Pizza withdrawals, so I racked my brain for a tasty alternative. What is a margherita pizza, anyway? It's basically dough and mozzarella and tomato and basil.
