Much lighter than a traditional chile relleno, each large piece of relleno casserole has just 240 calories and can be enjoyed with your favorite toppings.
Preheat oven to 350F degrees. Lightly spray an 11-inch x 7-inch baking dish with cooking spray.
Whisk the egg yolks and milk in a medium mixing bowl.
Whisk in the flour and salt until completely absorbed.
In a large mixing bowl, beat the egg whites with an electric hand mixer until soft peaks form. Carefully fold the egg yolk mixture into the egg whites until thoroughly combined.
Spoon a thin layer of egg mixture evenly over the bottom of the prepared baking dish. Place chilies over the egg mixture, being sure to cover the whole dish. Sprinkle cheese evenly over the chilies. Add the remaining egg mixture over the cheese and smooth evenly.
Bake 30-35 minutes, or until a toothpick inserted in the center comes out clean and the top is golden.
All pan to rest on a wire rack for at least 5 minutes before cutting. Serve warm.
Store any leftover casserole in an airtight container in the refrigerator.

Much lighter than a traditional chile relleno—which takes a large roasted poblano pepper and stuffs it with cheese, then is dipped in batter and deep fried until golden brown—each large piece of relleno casserole has just 240 calories and can be enjoyed with your favorite toppings.I loved the lightness of this casserole, but would have like a little more green Chile flavor. Next time I make this, I will an additional can (or two) of whole green chiles.
