Frozen Fruit Cobbler

2 bags (12 oz) frozen fruit, (I used mango, pineapple, strawberry, peach, banana by Dole)
1 white cake mix, (no pudding)
12 oz. diet 7-up, sierra mist, (clear soda)

Place frozen fruit in sprayed 9x13 dish. Add dry cake mix. Pour soda slowly over cake mix. Do NOT stir! Bake at 350 degrees for 50-60 minutes. I served it with sugar free vanilla ice cream/
