Place all ingredients (except for the banana) in a glass canning jar and stir very well.

Store overnight in the refrigerator, sealed or covered tightly.

In the morning, give the oats a little stir, slice your banana… top the oats with banana slices & a sprinkle of crumbled walnuts or pecans. (optional)

Yep! It’s meant to be eaten cold, like pudding – although you can heat if desired.
