I work for our schools so on the weekend, in a small crockpot, I make a week's worth of Steel Cut Oats (1 cup oats to 5 cups water) then place each serving in a to-go container that I reheat at work. I flavor my oats in many different way:
Splenda brown sugar, vanilla extract & cinnamon
Then add-in one of these combos:
diced apples & apple pie spice
raisins & chopped nuts (walnuts or almonds)
dried cranberrys & pumpkin pie spice
These oats stay with me much longer than the little packets of oatmeal plus I know what's in it.
I hope this gave you some ideas to try out.
Each serving of the oats contains protien, too.
I also substitute Farro which contains 7 grams of protein per serving & they are prepared the same way.
