Preheat the oven to 350°F. Arrange 5 oven-safe containers on a baking sheet and lightly spray with cooking spray.

Cut each biscuit into quarters. Place the pieces from one full biscuit into each container.

Heat a large skillet over medium-high heat. Cook the turkey sausage until fully cooked and no longer pink. Drain excess grease, remove from the pan, and set aside.

Using the same skillet (do not wipe it out), melt the butter over medium heat. Whisk in the flour — the mixture will be thick and clumpy at first.

Slowly whisk in the milk, about 2 tablespoons at a time, until smooth. Continue cooking and whisking until the gravy thickens.

Remove from heat and stir in the salt, pepper, garlic powder, and cooked sausage.

In a mixing bowl, whisk together the egg whites, whole eggs, and a pinch of salt and pepper.

Evenly pour the egg mixture over the biscuits in each container. Spoon the sausage gravy evenly over the top.

Bake for 30 minutes, or until the eggs are fully set and the biscuits are golden brown.
