10 Foods We'll Never Get To Eat Again (Slideshow)

Libby's was a creamy dressing that was lauded by its advertisement as a thrift food. Supposedly, you could use the dressing in a variety of recipes, thus eliminating the need for other sauces or ingredients. Unfortunately for Libby, it didn't turn out to be the wonder-food it claimed to be, as we can't find it anywhere anymore. 

The National Oats Company is no longer active, but the "pure white rolled oats" were popular in the '20s. In fact, one of the main advertising techniques was that eating National Oats would make your child "robust and active." 

Jell-Well Pudding Mix was pretty much the same as Jell-O, which is still in stores today. It was particularly popular in the 1950s, but we can't find a record of it after that. Jell-Well Puddings were 100 percent instant, and required no cooking. 

This may be one of McDonald's most embarrassing attempts at a vegetarian option. It was originally meant for Catholic customers who didn't eat meat on Fridays, but the "burger," which was just a slice of pineapple with melted cheddar cheese, did not please customers. In fact, the Filet-o-Fish ended up being the non-meat item of choice, and the Hula Burger was dropped. 

Even though Chef Boyardee products are still alive and kicking, this particular variation is not. It was a combination of meatballs, carrots, peas, potatoes and brown gravy that was meant to be eaten either by itself or as a part of a casserole. It was advertised as a thrift food, selling for only 15 cents per serving. 

This sugary kids' cereal only lasted for four years — it was on shelves in 1972, and off them in 1976. The Freakies were seven lovable, and slightly terrifying, characters who lived in a tree and had very interesting names, like Hamhose, Cowmumble, and Snorkledorf. 

O'Boises were potato chips that were very popular in the '80s. They were thicker than your typical Lays and came in three flavors: Regular, Sour Cream and Onion, and Barbecue. It's not exactly certain why O'Boises were dropped, but maybe the chips just couldn't keep up with their competitors.

Another popular snack from the '80s, Nabisco Swiss Cheese Crackers aren't around anymore, much to the dismay of some people. The crackers not only tasted like Swiss cheese, but they looked like it, too!

Gatorgum, which came from the makers of Gatorade, was a gum designed to quench thirst, while still being sugary and delicious. The gum was bright green, just like the drink, and of course was flavored like Gatorade.

This short-lived variation on Coke was flavored like coffee, and only made it two years, from 2006 to 2008, before being taken off the shelves. In fact, it was first introduced in France before it made its way to the States, but apparently the French version tasted more like coffee than a soft drink.
