A bit of brown sugar really helps bring a red sauce together and yogurt is good sweet or savory (granted I like my sweet yogurt to just be sweetened with fruit and no pure sugar added but that’s a preference thing)
As per usual in my responses to comments like this, just because it is easy for you to make these things doesn’t mean it is easy or practical for everyone to. From scratch takes longer, requires more knowledge which takes time to acquire, makes more dishes, requires more types of equipment, and in the case of yogurt can be a safety thing
It is on the companies making these products to do better not on the individual seeking to make a part of their life easier
I love fage, mixed with some roughly chopped cherries is so good. I’ve switched to making my own yogurt recently but the original starter I used was fage and it hasn’t let me down
