Cook the sausage by heating a non-stick skillet over medium heat and cooking breakfast sausage links for 5-7 minutes, turning occasionally until browned. Remove from pan and drain grease.

Scramble the eggs by adding a splash of butter to the skillet, whisking eggs, milk, salt, and pepper together, and cooking until just set, about 3-5 minutes.

Assemble the roll-ups by preheating oven to 375°F (190°C). Unroll the crescent roll dough into triangles, then fill each with cooked sausage, scrambled eggs, and cheese.

Bake the roll-ups by rolling the dough towards the point, placing on a lined baking sheet, and baking for 12-15 minutes until golden brown.
