Not prepackaged, sadly. But by making scrambled eggs in one skillet & s/b/s in the other, it doesn't take too much effort for once a week more or less.

I buy frozen scrambled egg patties and sausage patties from WalMart. They are fully cooked and can be heated in the microwave. Add two slices of Atkins bread and some cheese and you've got a quick low-carb Egg McMuffin.
