Croissant Breakfast Sandwiches

Preheat the oven to 350°F.

Slice the croissants in half horizontally and set aside.

In a skillet over medium heat, cook the bacon until crisp. Drain on paper towels.

In a bowl, whisk together eggs, milk, salt, and pepper. Melt butter in a nonstick skillet over medium-low heat. Pour in the eggs and cook, stirring gently, until just set and soft. Remove from heat.

If desired, spread a thin layer of mayonnaise or Dijon mustard inside each croissant.

Layer each bottom half of croissant with scrambled eggs, 2 slices of bacon, 1 slice of cheese, tomato, and spinach. Top with avocado slices if desired.

Place sandwich tops on and arrange the filled croissants on a baking sheet. Warm in the oven for 5 minutes, or until the cheese is melty and the croissants are heated through.

Serve hot and enjoy!
