Saute onion in olive oil until soft. Add garlic and peppers, continue to saute for 2 minutes. Remove from the heat and combine with ham, eggs, and cheese. To make turnovers, roll out dough and cut into 20, 3 inch diameter circles. Place a tablespoon of filling and half an olive on the dough. Fold pastry over to form a half moon. Seal with the tines of a fork and bake at 375 degrees for 25 minutes or until nicely browned.
