I picked up a bag of whole oat groats at my farmer's market. Most people grind them for flour. I discovered they make the best oatmeal ever. Not only are they more tasty then rolled or Steel cut oats they are also cost efficient.
They take a little more prep but are worth it and now part of my routine.
I make one cup dry and get 3 servings but you could double it and then simply reheat through the week.
Bring 3 1/2 cups of water to a boil
Add 1 cup oat groats
Simmer 5 mins
Set pan off heat and leave out covered overnight
In the morning simmer covered 20 mins
I eat it with fruit and cinnamon. So filling.
Of course if you are on high protein you could add your protein powder of choice.
