Preheat oven to 400℉. Brush about 1 tbs of olive oil on the bottom of the pan.
Add in the block of feta, eggs, tomatoes, Italian herb blend, salt, pepper and olive oil to the pan. Bake for 23-25 minutes or until mostly set. Immediately mix everything together in the pan and sprinkle with chives. Using a large scooper or spoon, scoop the mixture out evenly onto the English muffins.
