I remember this fondly from elementary school lunches. I was happy to find the recipe to recreate it. Don't judge the recipe based on the bad picture, I forgot to take one and had to take a picture of the leftovers. This jello is really good.
2 pkgs. cherry jello
2 c. boiling water
2 c. cold applesauce
Mix the jello with the water until dissolved. Add in the applesauce. Refrigerate until firm.
