"Find a way to eat oats!" — Jane and Ann Esselstyn at offset 4:47 of this video. Oats are available in many forms in the market. In this video, Ann shortlists three of them as best: oat groats (great but tough to eat), steel cut oats (awesome) and 'old-fashioned oats'/ thick rolled oats. Quick cook oats and other forms of oats are discouraged.
Below are recipes for overnight soaked oats, microwaved rolled oats, oat waffles, savory oatmeal and sweet oatmeal.
