Organic cottage cheese also contains active cultures. I get Horizon brand. The flavor is a little different from conventional cottage cheese, but not in a bad way.
What if you were to get vanilla yogurt (not plain- yuck!) and add banana slices? I think Kroger's store brand yogurt has a bananas foster flavor, but I've never tried it. I don't know of any strawberry yogurts, other than Whips, that don't have chunks of strawberry in them.
I picked up some Blue Bunny Light No Sugar Added Superfruit yogurt the other week, and that's been pretty good. The blackberry/lingonberry flavor had seeds, so I would skip that. But everything else has had little flecks of fruit, but not chunks.
