Rhubarb-Strawberry Dump Cake

While on my trip to Lancaster, Pa. I had to stop at a roadside stand and get some fresh rhubarb and strawberries. Here is a cake that I made:

4 cups cubed raw rhubarb
2 cups fresh sliced strawberries
3/4 cup sugar ( Splenda works)
3 oz. pkg. strawberry jello, dry ( diet works)
1 1/4 cup water
1/2 stick butter melted

Layer ingredients in order given in a 9 x 13 " baking pan. Do not mix. Bake in 350 degree oven for 35 min.
Serve plain or with cool whip on top. Makes 12 servings.
