Kind of ironic this guy is a farmer during harvest time and doesn't have access to food.
But in the interest of not being totally unhelpful, here's something that I like cold:
1 cup oats
A couple big spoonfuls of peanut butter (natural would be preferred)
2 cups water
microwave for 2 minutes, stir and try to separate the peanut butter so it's not as clumpy, then microwave for another minute. Add plenty of cinnamon and then a cup of frozen blueberries (4lb bag is like $8 at costco) and/or a banana or two.
It probably sounds/looks weird to eat cold (especially since the blueberries turn everything purple), but I almost like it better than way then hot. When I was roofing I would throw that in a cooler with a cold (but obviously not raw!) chicken breast and have a pretty damn good meal. You're getting about 1000 calories for less than $5 so it's nice on the wallet too.
I'm sure it won't be to everybody's taste, but don't knock it until you try it!
