Add cheese to well drained mixture.
Spread out pastry sheet and cut into 4-inch circles with a biscuit or tart cutter (a tuna can also makes a great cutter).
Brush with egg wash and place some of the mixture in the middle of the pastry circle. Fold over and crimp edges closed. Bake for about 12 minutes.
Served on a bed of lettuce with freshly made guacamole, diced bell peppers and onion. The empanada can be drizzled with crema or sour cream.
