Monteli. Trader Joe's sells the plain crust frozen (half baked). It is SO good. I put our own sauce and cheese on it. Not having to fool with flour and rolling dough is a huge time saver.
Wegman's frozen pizzas are the best I've had of the frozen pizzas. I won't claim that they're as good as a freshly made artisanal pizza but when you consider that it's only $5 compared to $20 at an artisanal place, they're fantastic value.
