For lunches, you need to prepare three or four main things you can
dish out and microwave. You need to invest in some good food containers,
like Tupperware, Rubbermaid, or Ziploc. I always pack my lunch, and my panniers
get heavy as hell sometimes, but if you apply the effort at home, a seriously nutritious
lunch and good snacks are easy to have every day.
Part of my morning routine is to assemble the day's food supply while my eggs
are boiling. For evening food, I think you need to cook on Sunday and have things ready
for the week ahead. Then if you have to depend on microwaveables, it'll be your own good stuff.
