Heat oven to 375°F. In large bowl, combine ground beef, bread crumbs, 1/2 cup of the pizza sauce and egg; mix well.
Divide mixture evenly into 8 ungreased muffin cups. Pat in bottom and up sides of cups to form beef cups. Fill cups with olives and cheese.
Bake at 375°F. for 15 to 20 minutes or until beef is thoroughly cooked. Meanwhile, heat remaining pizza sauce; serve with meat cups.
