Great tips. When I competed in figure competitions and was in my contest prep monde every sunday I would cook chicken and turkey breast, brown rice and sweet potato to last the week. I had individual serving plastic containers that I out a meat and a carb in and stuck them in the fridge or freezer so I could just grab some. I had a cooler that I actually kept in my truck when I had no fridge access.
It's hard when you are stuck somewhere and can't get away to eat, and don't have anywhere to store/cook food. There are always options to bring with you though, such as a tuna pouch and rice cakes.
