Here is an example of a Paleo like lunch. This is what was in the fridge when I went to get lunch. Lettuce, bacon, deli chicken (shaved), mayo and a few cashews because Rhys took one of my bacon strips.
I made a shell out of the lettuce, piled some chicken in, add mayo and one slice of bacon.

Lean meat – Chicken

Vegetables – Lettuce. I should have added peppers or something.

Nuts/Seeds – Almonds.

Fats – Mayo. Bacon
