Preheat your oven to 375°F (190°C).

Open the package of crescent rolls and carefully unroll them. Lay the dough flat in a greased 9x13 inch baking dish, pinching the seams together to create a continuous crust.

In a large mixing bowl, whisk together the eggs and milk until smooth. Add a sprinkle of salt and black pepper, then incorporate the diced ham, cheddar, and mozzarella cheeses. Stir gently until well combined.

Pour the egg and ham mixture over the prepared crescent rolls in the baking dish, spreading it evenly across the dough with a spatula.

Bake for 25-30 minutes or until the egg is set and the top is golden brown.

Let cool for a few minutes before serving. Optionally garnish with chopped green onions.
