I read something about using Greek Yogurt, I have some, so is there a way to use that to make an ice cream substitute without an ice cream maker.
guess plain freezing is it, and thanks for the frozen jell-o but i actually did that before because i put it in the freezer to make it firm faster. It froze and i just ate it anyway.

Answer
I don't know, but frozen jello is AMAZING!!!
