You've got to try this. Its a slice we like to get a lot and we've made the best one out there now. The place in NYC that we like the most for the Grandma's slice is Maffei's in Chelsea, and ours is just as good. They're both perfect is what I'm saying.
What is a Grandma Pizza? Rectangular, baked in a pan in olive oil. Mozzarella, smashed whole tomatoes, chopped garlic.
