Hello /ck/. I do not normally harass your board, being mostly confined to the fa/tg/uys, but I need some suggestions.

My father and I work as contract firefighters during the summer, and our job entails many days of sitting around doing nothing, punctuated by hours of frantic activity. The days are long, and we naturally have to provide our own meals. This year however, we want to find something cheap, filling, and somewhat healthy for us to munch on during the off-time, instead of our usual fair of Otter Pops and two-dollar microwave meals.

Any suggestions or ideas would be great. I'm not averse to cooking in advance, but the ideal food would be filling, give us some good energy, and cheap - but I'm fresh out of ideas. Many thanks in advance. Pic is related, I mix the pink goop.
