They call it a slice, that slab of pizza in front of you. It looks about the size of a laptop and sits on two paper plates. Cut from Pizza Rustica's signature square pans of the stuff, these are a meal cut into three-bite squares. They come with a laundry list of toppings, including imported prosciutto, yellow squash, and shiitake mushrooms. There's the campagnola -- with sweet sausage, roasted peppers, sweet onions, and plum tomato sauce. Or the pizza putanesca, covered in Sicilian anchovies, kalamata olives, jalapeños, red onions, and pepperoni. Finish them off with a pizza filled with hazelnut chocolate. The slices cost $2.75 to $3.75 and the full pies $11.50 to $29. But what makes these slices better than the competition is the fact that you don't have to leave the house: Pizza Rustica delivers any order of three slices or more. Why order so much? You don't need more than a slice for a meal. But if you order just a little, you have to leave the couch.
