The first time I made them, I didn’t think I’d like the oatmeal cold, but knew I could microwave them if needed. Turns out I prefer them cold. It’s along the lines of granola cereal that you let sit long enough to soften the crunch out of them. The big bonus is I can have them ready to eat when I roll out of bed and fill my coffee cup, instead of prepping and cooking them in the a.m.
Try them out one time. you don’t need to make them fancy, you can always heat it up if you don’t like it, and it’ll cost you very little.
