I eat a Jimmy Dean Breakfast Bowl (sausage, potatoes, egg, cheese, and gravy) (380 calories) every morning. I am a firm believer in a hearty breakfast. I could not start my day on something like fruit and/or cereal.

Not particularly "healthy," but very filling!
I hate to cook. I hate thinking about cooking. I do not cook. So, I eat lean cuisines or weight watchers smart ones for lunch and most suppers. (Under 300 calories). I'm also a very picky eater, probably only eat 25 foods altogether, and that's probably pushing it.
I'm a meat, cheese, and potatoes kind of a girl, so the frozen entrees I select are usually meatloaf with mashed potatoes, Swedish meatballs, salisbury steak, etc.
I love the lean cuisines and smart ones! And it really helps me monitor my calorie count. Simplicity in eating works best for me.
