My go-to oatmeal recipe is the one in the back of The Endurance Diet called Custard Oats (mentioned by someone else above as well). I just swap out the blueberries for whatever seasonal berry is on sale, so right now it’s bananas and strawberries. I find that the eggwhite is a huge help in making the bowl more filling because when I make oatmeal without it, I get a major hunger surge about 3 hours later.
I really want to try overnight oats for weekend rides since I start them earlier though. Anybody have a solid recipe that doesn’t include Greek yogurt (I hate the stuff)?
