My top three discontinued grocery store (junk food) items are:
Pizza Bake by Hambuger Helper
Sanderson's Farm Honey battered dipped corn dogs. Sams
and back in the late 90's Planters came out with a snack food that was in the shape of a peanut a crispy shell outside with a creamy peanut butter on the inside. They were so good. I would buy two or three bags at a time. I thought it would be fun to know what everybody missed.
Oh yeah! The 70's candy Space Dust it came in cherry, orange and grape flavors.
