Most of the jello salads I've so far seen I've decided haven't been much worth having. Gramma did like her jello, though its not necessarily a taste I concurrently enjoyed. This, with marshmallows suspended with childhood beauty, sounds like it be the winner of the bunch.
I mean, who -doesn't- like marshmallows?
1 small can
frozen orange juice
Dissolve Jello, add orange juice and enough mandarin to make 2 cups. Refrigerate until mushy -- add fruit and marshmallows.
