Cheese and heavy cream if you do some dairy. Homemade sour cream (or a variety of "yogurt" made with half and half). Cream cheese...may or may not be primal I suppose. Sorry to just throw out dairy sources, but thats what comes to mind if you already do coconu oil and coconut cream (the kind in the can) for smoothies and such. You could ditch the egg whites and eat a bunch of yolks too.
