i don't have any recipes but i have an idea .. i once had this homemade lemony ice cream with berry syrup (all home made) and OMG it was like heaven ...
another suggestion would be sorbet - doesn't have the calorie of dairy but watch out for hte sugar

have you looked up on foodnetwork.com and allrecipes.com for recipes? i'm sure they have some
