Preheat oven to 350° F and lightly coat a 9 x 13-inch baking dish with cooking spray.

Set whole green chilis on a clean dishcloth or paper towel to allow the liquid to drain.

Stuff each chili with a slice of cheese and set into the prepared baking dish in a single layer.

In a large bowl, whisk eggs, milk, flour, and chili powder until smooth.

Pour the egg mixture over the cheese-stuffed chilis.

Sprinkle the cheddar cheese over the top.

Place in the preheated oven and bake for 35 minutes or until the eggs are set and the top is lightly golden.

Let cool slightly, and then slice into 4 servings.

Serve with your favorite salsa, lettuce, tomatoes, green onions, and perhaps a dollop of Greek yogurt or homemade guac.

Enjoy!
