Preheat oven to 350 degrees. Brown beef; drain and combine with spaghetti sauce. Heat on low for 10-15 minutes. Meanwhile, grease a 9x13-inch baking pan. Slice biscuits into quarters and line pan with the pieces. Spoon some of the warm meat mixture over biscuits. Top with cheese, then with the remaining meat mixture. Add additional pizza toppings, if you wish. Bake until biscuits are done, about 15-20 minutes at 350 degrees.
