As with most of the dead cheap meals series, this recipe requires bone broth. While ham broth is preferred, beef broth, chicken broth or my mock broth would work also.
A small amount of ham processed from a half ham or leftovers is needed too.
Hubby insists yellow split peas are the bomb and taste entirely different from the green ones; I don't think it matters much.
Though peas don't have to be soaked in order to cook quickly, it is worthwhile to soak them anyway to remove phytic acid. And pressure cooking reduces lectins, so we wind up removing most of the anti-nutrients that the Paleo Peoples have issues with.
