Here's a little outline of what I would recommend eating in a typical day. Small glass of orange juice. 1 serving of fruit. 1 glass of tea or coffee. Plain baked potato.
Salsa makes a good topping.
So does a little tobasco or A1 sauce. For dressing, try a nice vinegarrette or low-fat variety of your favorite. Choose one that is low in saturated fat. A serving of fruit always makes a great snack. Some dry cereal may tide you over til dinner.
