How about making some egg muffins with sausage in them on a Sunday and freezing them. You can grab em on the go and they are really easy to prepare. This way you know exactly what goes into them.
Egg Muffins
Spray w/Pam a 12 hole muffin pan, put crumbled cooked sausage or cut up ham or bacon or whatever you like in the cups. Some broccoli or spinach or asparagus would be good too. Add grated cheese, cheddar or montery jack or swiss. Don't over fill it w/the meat & cheese, like about 1/2 way or 3/4 at most. Beat 8 eggs with lt cream or half and half, just a splash and spoon egg mixture into the cups. Bake 350 degrees, maybe 15 minutes or so, you'll see them start to brown.
The possibilities are endless, you can add any kind of cheese, meat or veggies, they are wonderful to freeze. In the mornings I like to grab one or two out of the freezer and by the time I get to work they are defrosted and ready to heat.
