Preheat oven to 375 degrees.
Layer in 9x13 casserole dish:
1. crescent rolls (1 can)
2. cooked and crumbled sausage (or crumbled bacon ~ I usually used pre-packaged Oscar Mayer bacon bits.)
3. mixture of 3 eggs, 1/4 cup milk, 2 level Tablespoons dried onion
4. grated cheddar
5. Bake approximately 20 minutes. It's done when it begins to brown on top.
