Nature Valley Protein Bars, Dark Chocolate Peanut Butter. Can be bought at Target or online, but the big box of 18 is at Costco (which is oly there, here and there, but they are back!). Turns out to be like 65 cents per bar. Get them while supplies last. 10 g protein, 14g carbs, 5g fiber–so net carbs is 9g. I use these as one of my protein snacks throughout the day and it tastes AWESOME! It is like having a dessert.
