Hi Selca - we were having the same problem. Breakfast is a shake of some sort, and dinner works itself out, but lunch was a real problem.
Have you checked out the Salad Nicoise? There are many parts in there that you can have separately - sort of like finger food. One of our favorites has come to be a 6 (or 7) ounce can of tuna, packed in water. You can throw it in your purse and pop the top at lunch. Add a bit of SB mayo, and it is pretty tasty. We put it over butter lettuce and add tomatoes.
Another good idea we had was Bay Shrimp, again over lettuce. Add avocado for added flavor.
We often have to buy salads when we are at work (you know how the mornings go sometimes) - Trader Joes has some good packaged ones. We just throw out the croutons.
Also - are you eating the cheese stick mid-morning? And nuts in the afternoon? Sometimes it helps to save those for lunch.
We really mix up the Daily menus to make it work for us.
Good luck
