Preparation of Oven: Commence by setting the oven to preheat at a temperature of 375ºF. Ensure even heat distribution for optimal baking.

Mixing of Ingredients: In a sufficiently large mixing bowl, meticulously combine the pre-cooked and crumbled breakfast sausage, room temperature cream cheese, and the well-drained Rotel tomatoes and green chilies. It is imperative to achieve a uniform mixture.

Preparation of Crescent Rolls: Carefully unroll the crescent rolls. With precision, bisect each triangle in half along its length, resulting in two elongated triangles.

Filling: Employing a small cookie scoop or a precise tablespoon measurement, place an adequate quantity of the earlier prepared sausage mixture on the broader end of each triangle. Subsequently, roll the dough towards its pointed terminus, ensuring the filling remains encased.

Baking: Arrange the filled crescents on a baking sheet, taking care to space them evenly. Place the sheet in the preheated oven and bake for approximately 15 minutes. The crescents should attain a golden-brown coloration indicative of their readiness. Once achieved, remove from the oven and allow them to cool slightly before serving.
