Preheat the oven to 375°F (190°C) and prepare a baking sheet with butter or parchment paper.
Extend the crescent dough into a rectangular shape, ensuring to pinch the seams together.
In a bowl, whisk together eggs, milk, salt, and pepper, then mix in cooked sausage and cheddar cheese.
Spread the egg mixture over the dough, roll it into a log, and cut into 8 pieces.
Place the slices on the baking sheet and bake for 15-20 minutes until golden brown.
Serve warm, optionally garnished with herbs or extra cheese.
