We may eat a lot of pizza in our home, but I don’t think we have big enough stomaches to eat this extra-extra-large pizza:

A pizzeria is vying for a spot in Guinness World Records for the world’s largest commercially available pizza. The $99, 150-slice pizza isn’t a one-time deal. In fact, The Big One is already available, though Mama Lena’s Pizza House has had few takers so far.

The would-be recordsetter measures about 3 feet by 4 1/2 feet and takes up nearly all the space in the shop’s brick oven.

The current record holder is a 4-foot diameter pizza offered by Paul Revere’s Pizza in Mount Pleasant, Iowa. Dubbed the Ultimate Party Pizza, it uses more than 10 pounds of dough, 48 ounces of sauce and about five pounds of cheese.

A tip for Mama Lena customers: Call ahead. The Big One takes about 15 minutes to prepare and another 20 to 25 minutes to bake, said Rob Carrabbia, whose wife, Wendy, owns the pizzeria in the suburban Pittsburgh town of McKees Rocks.
