5. Peanut Butter
Peanuts are one of the most protein-dense nuts, ounce for ounce. Rip the top off a single-serve squeeze pack and eat the butter straight from the pouch when you’re on the go. It’s very satisfying, believe us. For more of a sit-down snack, smear some sweet and salty spread onto a sliced apple.
A two-ounce serving promises 14 grams of protein and a helping of heart-healthy monounsaturated fats. Just reach for the natural variety with little to no added sugar.
