Late night protein cravings are best solved with unsalted peanuts, cottage cheese or tuna straight outta the can smothered in some hot sauce. Cottage cheese can be addicting though watch out i look down sometimes and ive ate a whole fucking container. Peanuts are great unsalted , have a lot of protein but also significant fat, bout 25% regular, 10 % saturated per serving. I leave a lot of plain chicken lying around too, satisfies and has good protein and no carbs so its great for night.
