Step 1

Preheat the oven to 375 degrees F. Lightly coat a 7- by 11-inch baking dish with cooking spray.

Step 2

Bring a medium saucepan of water to a boil. Add the broccoli and cook until tender-crisp, about 2 minutes. Drain and rinse with cold water to stop the broccoli from cooking further. Transfer the broccoli to the prepared baking dish.

Step 3

In a large bowl, whisk together the eggs, egg whites, water, smoked paprika, salt and pepper.

Step 4

Pour the egg mixture over the broccoli and sprinkle the feta cheese over top.

Step 5

Bake until the casserole is set and a knife inserted in the center comes out clean, about 20 minutes.

Step 6

Cut into 6 pieces. Serve.
