Howdy.
Pizza sounds good to me.
No, I haven’t used oats in cookie dough, LOL, but have sneaked it into lots of other things over the years and always in meatloaf, pancakes and any place it would go, with the bread machine, I use regular oatmeal to take up the extra liquid, if I have to add it after it is mixed.
On the last thread, I posted an old recipe, for a fruit cocktail cake that used cooked oatmeal in it, someone invented it many years ago, to use up leftover mornings oatmeal.
It was my stepfathers favorite cake.
You can also season, add onions and an egg to leftover oatmeal and maybe even a dab of flour so it will hold together to make a patty and then roll in cornmeal and fry in bacon drippings and it makes a tasty patty.
Why not run a handful of dry oats through the blender and use it for breading chicken, squash or? with seasoning in it, it should be very good.
