Preheat the oven to 325 degrees.
While the oven is heating up, prepare the broccoli by following the directions on the bag. Drain the excess water from the broccoli and cut it into small pieces. Let the broccoli cool before adding in with the eggs.
As the broccoli is cooling, crack the eggs into a medium bowl and add the salt, pepper, granulated garlic, and onion powder. Whisk until the eggs and spices are blended.
Slowly whisk in the romano cheese. Set aside.
Pour the egg mixture into a 9 x 13 ceramic baking dish sprayed with cooking spray.
Add the broccoli and shredded cheese to the egg mixture and slowly stir just until evenly distributed.
Place the casserole dish into the oven and bake for 35 - 40 minutes or until the eggs are set in the middle.
Remove from the oven, cut into 12 pieces and serve.
