Dash of sea salt or some salt
A little salt (I use just a little sea salt)
Black pepper to taste
Greek yogurt (or sour cream) [I use Greek 2% yogurt and for what we can get in the US, it MUST be Fage (Fa-yay) brand for me. The others are nowhere near the real deal like in Greece!]
Layer and eat, that's all there is to it!
* Obviously when using for leftovers, in a bowl in a microwave heat your beans, corn, rice and protein/meat, then layer everything else on top!
