OK, I tried them? water to boil add oats, simmer for 30 minutes.
IDK, are they supposed to have the texture of rubber bird shot. A little tougher than tapioca or rice?
Or were they not cooked long enough.
If they are tough or chewy and you don't like them that way just cook them a little longer. I usually stick mine in the microwave with butter and some kind of dried fruit ... whatever is handy -- raisins, cranberries, apples, cherries ... whatever ... a little milk and honey sometimes if the fruit doesn't sweeten it up enough and I am good to go.
I like rolled oats too ...
Microwave is the fastest way to cook them. If you cook them on the stove treat it like rice ... boil the water, then turn it down and let it simmer for 30 minutes or so ... you don't have to keep stirring.
