I like to make turkey feta basil burgers. Though that recipe uses "hard" feta crumbles, so it may not work if you got the softer variety.
I sometimes make a version of manoush - homemade pizza with a zataar topping. It’s fantastic fresh out of the oven eaten with feta and sliced tomato and cucumber. Also, Feta Coleslaw is delicious. (I know, sounds weird, right?). That recipe makes enough for an army, so I always halve it and it's still plenty for two people for a couple of meals.
