Preheat your oven or toaster oven to 350 degrees F.
Place the bottom half of each croissant on a baking tray.
2 croissants, sliced in half
Top each croissant half with two slices of bacon and one slice of cheese on top of the bacon.
4 slices cooked bacon, 2 slices of cheddar cheese
In a medium sized bowl, whisk together the eggs, milk, salt, and pepper.
3 eggs, 2 Tablespoons milk, 1/4 teaspoon salt, 1/4 teaspoon ground black pepper
Add the olive oil to a large skillet and heat over medium-high heat.
1 Tablespoon olive oil
Pour the egg mix into the hot skillet and stir. Stir the eggs slowly, scraping the bottom of the pan, until the eggs are almost cooked to your liking. Stir in the pepper jack cheese and then finish cooking the eggs until they are done to suit your tastes.
1/2 cup shredded pepper jack cheese
Divide the cheesy egg mix between the two croissants on the tray, scooping the eggs directly on top of the cheese.
Top each sandwich with the croissant top then place the sandwiches in the hot oven for 5 minutes to melt the cheese.
