Is There a Low Cost Protein That You Can Use?

i make a really delicious sardine pate, which is really just sardine and butter. Duck fat, i love duck fat. Like duck fat fries or just delicious. But if i eat them, i'm not a happy person. I like cocoanut oil and avacato and olive oil and olives than i do with animal base fat. You can deftly use clarified butter, which is gay. It's an option for people who might be dairy sensitive.
