I love feta in a greek style omelet.
Feta also plays well with beets. We peel the beets, then roast in foil having coated them with olive oil, salt, and pepper (much better than boiling). After cooled, slice or dice them and use in a mixed green salad with fresh thyme and shallot in the o & v dressing. Crumble feta on top.
The tartness of the feta and the sweet beets are great together.
