Tuna salad (1/4 mashed avocado, 1/2 can of tuna, diced sun-dried tomatoes OR capers OR diced beets OR sliced olives OR whatever else sounds good, diced red onion and/or celery, 1 Tbsp dill or sweet relish, seasonings to taste) on a Flatout wrap with lots of dark leafy greens.

Half a cup of black or kidney beans, a quarter cup of garbanzo beans, half a diced tomato, a quarter of a diced cucumber, a quarter cup of diced red onions with a dressing made of 1tsp Splenda, 1Tbsp olive oil, balsamic vinegar to taste, and white pepper. Sort of a cross between 3-bean salad and gazpacho.

An eighth of a cubed watermelon or other seasonal melon, 1/4 cup chopped strawberries, 1/4 cup blueberries, 2-3tsp chopped mint or basil, and 1/2 cup of lowfat cottage cheese or ricotta.

A wedge of Laughing Cow mixed with finely diced sun-dried tomatoes and/or black olives and diced green onion, spread on a bagel thin, with 2-4oz grilled chicken breast and plenty of spinach.

A cold baked potato, a cold hard-boiled egg, a stick of low-fat string cheese, and a quick salad of dark greens + diced tomatoes, with a little container of whatever seasonings you'd like for the potato & egg (I personally enjoy Accent, garlic powder, dill, and sea salt -- not all together).

Another cold potato and boiled egg, this time chopped roughly and tossed with a stick of diced celery, a sprinkling of diced red onion, a teaspoon of dill, a teaspoon of olive oil, and a healthy splash of balsamic vinegar. As an alternate dressing option, use pickled beet juice mixed with lemon juice (this is my new favorite Everything Dressing; it's crazy delicious). Put a one-cup scoop of this potato-egg salad on a bed of, you guessed it, dark leafy greens and sprinkle an ounce or so of Parmesan on top.

There is a book called the lunchbox diet and it has some really great lunches that are low calorie.
You throw everything in and shake the lunchbox!
