Pizza Casserole

1 pound ground beef
1 - 15 ounce jar spaghetti sauce (I used Ragu)
1 egg
1 cup milk
1 cup bisquick
8 ounces mozzarella cheese (or whatever you have on hand)
1/3 cup parmesan cheese (ditto)
1/2 cup chopped pepperoni (mainly I chopped it because I have toddlers)

Brown ground beef and drain. Pour meat into casserole dish. Add pizza sauce and pepperoni, layer a bit of cheese on top. In a seperate bolw add egg, milk, oil and Bisquick. Mix well. Pour mixture over ground beef. Bake at 350 degrees for 25 to 30 minutes. Bisquick mix should be brown. Add cheeses on top and bake another 5 minutes or until cheese is melted.
