I’ve tried a few types of coconut-based yogurts that were tasty. I’m not a fan of almond milk, so didn’t like those varieties as much. On the cheeses though, completely agree! I had one that was tolerable, but definitely falls in the “not good” category.
The vanilla flavored one was a bit sweet, but that’s how I generally prefer it. I usually am throwing berries and granola in there too so admittedly can’t give you an unbiased recommendation! I think there are plain flavored ones either almond or coconut milk based, which might be more of what you’re looking for.
