Here's another recipe that I got from Taste of Home magazine several years ago. I suspect that it would be even better with twice as much pizza sauce (since I love pizza sauce and am still recovering from a childhood where my dad would order our pizzas with NO SAUCE!), but I've never remembered to try it that way.
2 tubes crescent rolls
1-1/2 lbs ground beef
1 15-oz jar pizza sauce
2 c. mozzarella sauce, shredded
Preheat oven to 350F.Unroll one tube of crescent rolls; place in a lightly greased 9x13" baking dish. Press to seal perforations. Set aside. Brown ground beef; drain. Sprinkle beef over dough. Top with pizza sauce and cheese. Unroll remaining tube of crescent rolls; place over cheese layer and press to seal perforations. Bake for 30 minutes.
