Vanilla - you can put any topping on it and it'll taste good.

Banana is another good one~~

Watermelon flavor ice cream that is naturally flavored. Kroger sells it as a seasonal item so it is not available now.

Unfortunately, there is only one supplier and that is Kroger with their house brand. It uses flattish chocolate pieces to resemble the seeds and is naturally flavored with watermelon concentrate. Unfortunately, all that watermelon liquid makes it more of a sorbet than an ice cream. It's still pretty creamy though and I'd say it is halfway between a sherbet and an ice cream.
