depends on what body type you are as to what you can have at various meals. I pre-package everything in "serving" sizes, so I can just grab and go. I guess you're talking more about just a meal or 2 on the run, as opposed to days and days without refrigeration? Most proteins will travel OK for small periods of time without refrigeration - can't tell you how much chicken and turkey that I've eaten at room temperature! Brown rice is good as a carb at room temperature. I've made the Chocolate Muffins from the RE, they're OK, but not as chocolate-y or muffin-y as they sound. Not sure about the pop-top salmon or chicken breast, you'd have to read the list of ingredients on the label. If it has salt or sodium (even sea salt), it's not on plan. I'd also rather doubt that the egg drop soup is prepared without salt.
If you can have fruit, baby food is passable, too. Stage 3 bananas are the right proportion, and is on plan, too.
A great place to check would perhaps be the food services thread in New Body U. I think almost every semester they have a dorm that does something with "portable food".
