Preheat oven to 350.  Brown the meat in skillet.  Stirring until crumbly and drain. You could add an onion but my kids won't eat anything with onion in it.   Stir in sphegetti sauce.  The recipe calls for a 15 oz jar and I used it all.  Season as you want - I added some basil and more garlic.  Don't add water.  Simmer for 5 minutes or so.  Spread mixture in a 10x10 casserole dish. 
Sprinkle on the mozzarella cheese and then half of the parmesan cheese.  Cover with the crescent rolls pinching them together. 
Sprinkle with remainder of parmesan cheese.  Bake for 15 min. or until golden brown.  That's it.
