This gelatin mold was a staple at our summer get-togethers. It was easy to make, it was cool, the kids all loved it, it is chock full of fruit and vegetables, and adds a pretty color to any picnic table.
Make a small box of lemon Jell-o as per package directions (orange would also work)
When its just about set, stir in the following:
1 cup grated carrots
1 can of pineapple chunks (drained)
Refrigerate a few more hours until set.
