Vitatops are tasty though I haven't eaten them often since I joined WW. I used to get them at Costco for a good price and keep them in the freezer, but no idea what that price is now. I would put them in my microwave for 30 seconds and they'd be all warm and gooey.
Skinny Cow's new heavenly crisp candy bar in peanut butter is also crazy good but even less filling for 3 pts imo.
For 3 points something like a nonfat greek yogurt just keeps me full for a lot longer.
