Breakfast is usually either toast, or oatmeal and fruit, with coffee and juice.
Lunch when I am working is usually a Lean Cuisine meal and yogurt with fruit.
Supper...depends on what is in the house. Once or twice I cook supper, and then eat that for the next several days. Or on weekends I will make a big pot of soup and eat that, usually with some good bread, and a salad.
I do like to cook, but it isn't always fun cooking for one, so I go in spurts. Once in awhile, instead of really cooking a meal, I will have popcorn for supper, along with a slice of cheese, some fruit, and some veggies...sounds kinda strange, but it gets in all the food groups, and it fills me up.
