Preheat oven to 375 degrees. Place the croissants on a baking sheet. Cut a rectangle out of the center to make a boat.
In a small bowl, melt the butter and combine with chipotle sauce.
Whisk the eggs together with half the chipotle butter. Season with salt and pepper.
Place the crumbled sausage in the bottom of the croissants. Pour in the eggs. Top with gruyere cheese.
Bake for 12-15 minutes, or until eggs are set and cheese is bubbling.
Brush the outsides of the croissants with chipotle butter. Sprinkle fresh chives on top.
