Italian Crescent Casserole

I haven't made this dish in a long time but I thought I would pass it on because it is sooo good. Maybe I'll make it this weekend......

Preheat oven to 375 degrees

Ingredients:
1 pound ground beef
1/2 cup chopped onions
1 jar spaghetti sauce
1 (8 ounce) can tomato sauce
1/2 cup sour cream
1 1/2 cup Monterey Jack cheese
1 can of 8 crescent rolls
1/3 cup grated Parmesan cheese
2 tablespoons butter (margarine)

Directions:
Brown beef w/onions; drain. Stir in spaghetti sauce and tomato sauce. Heat until bubbly. Combine Monterey Jack cheese and sour cream. Pour meat into ungreased 12x9 inch pan. Spoon cheese mixture over meat. Separate crescent rolls into 2 rectangles. Place over cheese. Combine Parmesan cheese and butter; crumble over crescent dough. Bake, uncovered, 18-25 minutes or until center is golden brown.
