While pan is cooling, prepare the other ingredients:
Pat dry pan once cooled and prepare pan by coating the pan with butter or oil and anchovy oil. Preheat oven to 350. Pour egg mixture into pan, then sprinkle vegetable mixture over egg evenly pressing down to lightly coat top with with egg mixture. Place in oven for 10 minutes - check firmness. Turn once, place back in oven for 5- 8 minutes. Remove when firm, edges slightly pulling away from pan and let rest. Serve with sweet potato fries.
Sweet potato fries
Heat a few cups of canola oil (about two or three inches deep) in a 5 qt. cast iron pot to about 350/375 degrees.
In one medium mixing bowl mix flax, oats and bread crumbs and in another mix eggs and milk to create your dredge stations. (if you wanted to do two, add one more station with plain flour and the egg mixture. This station goes first.)
Cut your sweet potatoes into long thin sticks. Dip sweet potato sticks into egg mixture, then into oats mixture, then place in fryer for 2-3 minutes. Place on drying rack or paper towels. Repeat until you go through all sweet potatoes. Sprinkle sea salt and ground pepper over hot sweet potatoes.
