Thank Christ for Instructables. Without the DIY-themed site, I wouldn’t be able to to build a pizza oven in my backyard. That’s right. With a free weekend, underpaid laborers from a Home Depot and a few goombas, you and your “crew” can craft the ultimate earth oven. Bake ziti. Bake Rock N’ Roll pizza. Bake lasagna. Just make sure you don’t bake your girlfriend. A garbage disposal works much better.
