This is a completely paleo version of the recipe but there are tons of ways to switch it up if that’s not what you’re looking for. This version of the recipe is gluten free, grainless, dairy free, paleo, nut free, soy free and refined sugar free. Check below for vegetarian, vegan and other alternatives.
