It takes about 1/3 to 1/2 the can of sauce, and maybe half the mozzerella. Make the pizza crust as directed on the box. While it is standing for the 5 minutes, grate the mozzerella, about 1/4 the cheddar, and grease the pan. (I use a cookie sheet, which the $.45 crust just covers.) Spread the crust, pour on the sauce, spread the sauce with a handy fork. Dump the cheese on and spread it around. The cheddar adds just a bit of flavor, while the mozzerella takes care of the texture. Frankly, I like provolone better, but it's just not traditional. Place the salami close together and overlapping. Sprinkle mushrooms over the top, and break olives in two. Use the whole can to heck with the diet!
