Made it for Sunday dinner. Used cherry jello and strawberry yogurt. Don't know why one couldn't use regular jello. I made my own graham cracker crust. Just guessed and mixed together graham cracker crumbs, sugar, and a little melted oleo. Patted it out in pan and baked it for a few minutes. My husband loved it. Ate two pieces. I will make it again. Fruit could be added and one could use several flavors of jello and yogurt to very the taste.
