Well, I was going to give you a horrible idea, but it looks like you already have 9 of those.
This is what I ate for about 3 years:
Take a tortilla (whole wheat, sun-dried tomato) and add humus and/or mustard to it. Add cheese, lettuce, pickles, tomatoes, and a little balsamic vinegar/dressing. Wrap with paper towel and tinfoil.
For a side, take fruit and whole vegetable like a bell pepper, which is actually really good and sweet by itself. Alternatively, you can make a salad with basically the same ingredients.
For a drink, buy a can of Diet Coke.
