Recipes to use up poor quality feta?

I bought feta for the first time today. Unfortunately I hate the one I bought. It's called "Treasure Cave" and has an unappealing dry, powdery texture. When I was buying it, I didn't realize that it was not real feta but rather the equivalent of that powdery parmesan in the canister with the green top. Anyway, I don't want to waste the whole tub. Any ideas for what to do with it?

There are some good-sounding ideas in this thread:

Do any of these seem like they might be able to disguise the texture of my feta?

Thanks in advance!
