Maybe try incorporating choices from the different areas to make your own unique entrees, like grilled chicken on your salad,or some of the lunch meat from the deli bar like a chef salad. I like to put lots of greens in my wraps, sometimes I just make a salad wrap, if you like a little spicy mix salsa with a little ranch dressing.
When I'm traveling and limited in food choices I try to look at vegetarian options for ideas for healthier choices. Broth based soups are good, I've seen guys put their cooked veggies in their soup to bulk it up.
Best of luck to you
