When considering lunch and other food options, I plan on buying items that are mobile or convenient. I've had to do that in college and during the last couple transfers of my mission. In total, that has consisted of about seven or eight years of my life. Nowadays I plan my lunches based on whether or not they're healthy and can fit in my backpack. And cheap.
I wonder what kinds of foods I'll eat when I am done with school. I'll go to work and continue with the tradition of packing a lunch. But some day I will stay at home and be a mom, in which case I can consider lots of other food options.
