Preheat oven to 400°. Place mini fillo shells on a baking sheet lined with parchment paper or tin foil.
In a small mixing bowl, combine ham, sausage, bacon, green onions and cheese. Divide the mixture evenly between the Fillo shells.
In a mixing bowl preferably with a pouring spout, whisk together eggs, milk, salt and pepper. Pour the egg mixture on top of the meat mixture in the Fillo shells.
Bake 8 - 10 minutes until the center is set and puffed.
