You can bake potatoes in the microwave. Put them in a bowl with a quarter cup of water, and put a small plate on top. Its about 6-7 minutes and a lot better than oats, or at least an alternative.
Plus there are semi-cooked rice trays that are fantastic and take 90 seconds in the microwave to finish. There are about 3 different brands.
I'd much rather have rice or potatoes. Also you can get some shelf stable oils like Ghee, coconut butter, red palm, as alternatives to olive oil.
Potatoes or rice and eggs with veggies sounds a lot better than oatmeal to me.
