Overnight oats

I usually only make them when I have a near-empty jar of nut butter. Then I just add oats and milk. Stir.
In the morning I will usually add protein powder and maybe some sort of fruit or something if I'm feeling fancy.

I should have added that I halve the recipe, and it's plenty for a couple of breakfasts!

I usually do a chocolate mix. I add rolled oats, almond milk, cocoa powder, sugar or Splenda to taste, espresso powder, a few of mini chocolate chips, cinnamon, and half of a banana sliced. It's usually a tad less than 400 calories depending on how big the banana. Sometimes I eat it cold but it is something special (like dessert...lol) if I microwave it for about 30 seconds.
