3 cups broccoli florets (fresh or frozen)
2 cups cooked beef, diced
8-10 eggs, beaten
1 cup feta cheese, diced or in thick chunks
1 cup shredded cheddar cheese
¼ cup milk
½ cup yellow onion, diced
2 teaspoons salt
1 teaspoon pepper
Preheat oven to 375°F. Coat a 9 x 12-inch pan with cooking spray.
If using frozen broccoli, thaw and drain any excess water before adding to dish. If using fresh broccoli, trim florets and steam or blanch briefly. To blanch broccoli, simply place broccoli florets into a pot of salted boiling water for 2 minutes. Use a slotted spoon to immediately transfer broccoli into a bowl of ice water (this will stop the cooking process). Cool completely in the ice water, then drain on a towel before adding to remaining ingredients.
In a large bowl, whisk eggs with milk and season with salt and pepper.
Scatter broccoli, beef, and onion into baking dish, then pour in egg mixture and sprinkle cheeses over the top.
Bake for 30-40 minutes or until edges begin to golden. Serve warm and enjoy!
