Lunchables are pre packaged lunches you buy at the store. They usually feature like meat and crackers or pita bread and pizza ingredients. The fun is in putting them together the way you want. They always come with some kind of dessert like a peanut butter cup or Oreos. If you got the expensive lunchable it came with a Capri Sun drink in it too!
They were always awesome when I was a kid, and even today at 42 years old I still get one at the store now and then when I'm feeling nostalgic lol
