What is your unconventional prep. Something that you think is uncommon or weird, but will always keep extras of?
Personally I've been really big on keeping canned pumpkin on hand. While it's not the most nutrient dense food around it has the most fiber out of any canned item I can find and adds a new taste to everything. Goes great in mashed potatoes and soup.
Uncommon because I don't hear it being pushed a lot for food, but oats. They're cheap (about the same price point as many beans, about $0.60-$1/lb), but are such a fantastic, well rounded food. Protein, fiber, carbs, are good for blood sugar and cholesterol, and can be eaten alone or used as a filler for breads, meatloafs, and other baked goods. They also don't take as much water to cook as dried beans do.
Sealed in mylar with O2 absorbers, steel cut oats easily have a 15 year shelf life. Cook time, maybe 5-10 minutes.
Uncut oats can do 25+ years, but they aren't as much "pull out and cook" as steel cut are.
I thought so too but plain cold water doesn't seem to flow thru them very well. However, it would need to be then boiled anyway so might as well start by boiling it first and then filtering it.
