Another great jello salad!
Make jello and pour half of it into bottom of pan or mold. Chill just until barely set, then stir in some strawberry and banana slices. Chill until firm.
Carefully spread sour cream over bottom layer.
Allow remainder of Jello to cool to room temperature, then stir in more strawberry and banana slices. Carefully pour over sour cream. Chill until firm.
