If you're not a fan of blue cheese, I get you! I wasn't always a fan and even now, it has to be on the mild side to enjoy it. Here's what I would switch it up with: Feta because it's briney and a little funky, I'd also try fresh mozzarella or even burrata but since it's so milky, I'd plate it, whole, in the center of the salad and only break it up as it is being served to people.
