I like to reheat left overs from dinner,
Tuna Sandwiches either in a wheat pita or whole wheat bread with either some pretzles or some fruit of some sort.
Lean Cusine meal when im in a hurry and had no time to prepare
some times I will have ceral with a small fruit bowl.
You could buy a sub from subway
I like Quiznos subs
and any wraps listed as either low cal or lat fat
I am on the move alot at work , I do a lot of walking and lifting and need the protein and the fuel to keep my body working so my meals might differ from what you need.
alot of it depends on if you have the time to prepare your meals
and if you have the time to get your lunch ready for the next day.
Also what way your changing your eating habits, such as low cal, low fat, etc....
Good Luck and I hope you find what you need.
