Actually, it's a food that I loved, I forget what brand name it was, but it was the delicious popcorn chips (not the crappy Popchips brand either), that actually TASTED like buttered popcorn, and I was so bummed when they stopped making them. Also the Cheetos paw shaped cheezies, they were awesome!
Other than that, I can't really think of anything off the top of my head.
Edited to add Tart n Tiny's, and green Sweettarts and Shockers that used to be lime flavored (now they are an artificial green apple flavor), Pepsi Twist or Lemon Coke (sorry Lime Pepsi just isn't the same), Cherry Pepsi/Coke in Canada, Cinnamon Scope (can't find it here in Canada), Salt & Vinegar Ruffles chips, Hershey Pieces (like Smarties or M&M's but with Hershey chocolate inside), Hershey Kissables (baby candy coated Hershey Kisses), Rice Krispy Treat cereal (in Canada),
