Preheat the oven to 350°F. Spray the bottom and sides of a small oven-safe dish. I used a 5-inch ramekin with 3-inch sides. Fold 5 sheets of phyllo dough in half and press into the ramekin, tuck any dough that overhangs into the ramekin. Place ramekins on a sheet pan. Brush the olive oil over the dough. This helps it brown.
In a medium-sized bowl, beat the eggs. Add green onion, salt, and pepper to eggs and combine. Add half of the ham, bacon, and ¼ cup of cheese to each ramekin. Carefully pour in eggs. Top each ramekin with the remaining ½ cup cheese (adding ¼ cup to each ramekin).
Bake at 350°F for 20 to 25 minutes until lightly set in the center. Remove and allow to cool 5 minutes before serving.
