Step-by-Step Instructions:
1. Preheat the Oven:
Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper to prevent sticking.

2. Prepare the Sausage Links:
If using raw sausage, cook the links in a skillet over medium heat until fully cooked. Let them cool slightly before handling.

3. Roll Out the Dough:
Open the can of crescent roll dough and separate it into triangles along the perforations. Lay the triangles flat on the parchment-lined baking sheet.

4. Add the Filling:

Place a sausage link at the wide end of each crescent triangle. If desired, sprinkle a little shredded cheddar cheese over the sausage before rolling.
5. Roll the Crescents:
Starting at the wide end, roll up each triangle, encasing the sausage inside. Place the rolls seam-side down on the baking sheet to prevent them from unraveling while baking.

6. Brush and Garnish:
Using a pastry brush, lightly coat the tops of the crescent rolls with the beaten egg. If you like, sprinkle sesame or poppy seeds on top for added texture and flavor.

7. Bake:
Bake in the preheated oven for 12-15 minutes, or until the crescent rolls are golden brown and flaky.

8. Cool and Serve:
Remove the rolls from the oven and let them cool for a few minutes before serving. They’re best enjoyed warm!

Tips for Success:
Pre-cooked Sausage: Save time by using fully cooked sausage links. If using raw sausage, ensure they’re thoroughly cooked before rolling them in the dough.

Cheese Options: Try swapping cheddar for other cheeses like pepper jack or mozzarella for a flavor twist.

Dipping Sauce: Serve these crescent rolls with ketchup, mustard, or a creamy dipping sauce for extra flavor.

Make Ahead: You can prepare these rolls the night before and refrigerate them. Bake fresh in the morning for a hot, flaky breakfast.
