What are protein balls?

LYNN'S PEANUT BUTTER OATMEAL PROTEIN BALLS OR BARS (Makes 16 bars or 48 balls) Healthy high protein snack. Consistency of a soft caramel. Delicious! Ingredients: 1 cup reduced fat peanut butter 1 cup no sugar added applesauce 1 cup oatmeal (regular oatmeal, not instant) 1 1/2 cups dry nonfat instant milk 6 scoops (2 cups) GNC Pro Performance 100% Whey Protein (Flavor of your choice. I use Chocolate Caramel.) Directions: Microwave the peanut butter and applesauce about 2 minutes. Stir until well mixed. Add oatmeal, protein powder, and instant milk. Mix well. (It gets thick, so you'll have to use a food processor or your hands to mix it.) Wet hands and roll mixture into 48 walnut sized balls, or with the back of a wet spoon press into loaf pan sprayed with Pam. Chill, then cut into 16 bars and store in plastic bag in refrigerator.
