I wanted to make grilled halloumi but couldn't find any, so I bought some feta and found that you can grill it as long as it's in a little tinfoil packet. This is a great appetizer or accompaniment to a light dinner of Greek salad and chicken souvlaki. You can really add in whatever you want for seasoning. I kept it pretty simple with grape tomatoes, herbs de provence, lemon, and garlic, but you could add cooked tomatoes, capers, chilies, olives... The cheese gets hot and melty and it's super tasty, and couldn't be easier.
