Hi there, welcome to the boards.
Here are a few ideas:
Breakfasts- Oatmeal, Boiled eggs which you can make the night before, Fibre 1 cereal with skim milk, Grapefruit.
Lunch- Spinach salad with strawberries and a lowfat poppyseed dressing. Regular green salad with a chicken breast or lowfat turkey deli meat.
Cottage cheese, Peanut butter sandwich on WW bread.
Dinner- Salmon, Chicken Breasts, Sole, veggies of almost any kind, Steamed Broccali, cauliflower, beans etc. and a salad. I sometimes make wild rice.
Snacks- Jello, Low fat rice pudding, frozen grapes(awesome) Low fat graham crackers, oranges.
Those a just a few ideas.
If you do a menu at the beginning of the week, things are easier to follow. Thats what I have been doing recently. On Sunday, I make my menu for the week and then I go buy my groceries.
