Ingredients
Directions
Melt the butter and olive oil in a medium cast iron skillet
Sauté the onions and Swiss chard stems for several minutes. Add the diced ham and cook for an additional 2 minutes. Add chard leaves and cook until wilted
Remove from heat while preparing the eggs and cheese
Whisk eggs, milk, salt, and pepper in a medium bowl
Return the pan to heat and add egg mixture. Sprinkle top with cheese. Cook until set, about 4 minutes
Place the cast iron skillet in the oven on low broil for several minutes until the top is browned. Be very careful to use a hot mitt when removing the pan from the oven
Let the frittata sit in the pan for 1–2 minutes, then run the spatula around and under it, carefully sliding it onto a plate. Cut and serve
