I came up with this when I was in the mood for a Greek omelet but wanted enough to feed a family without spending all evening in the kitchen. Make once and done! Perfect for those breakfast-for-dinner days.

Recipe Instructions
Step 1
Bake in the preheated oven until eggs are set, 30 to 35 minutes.
Step 2
Preheat the oven to 350 degrees F (175 degrees C). Grease a 9x13-inch casserole dish with cooking spray.
Step 3
Melt butter in a medium skillet over medium heat. Add onions and cook, stirring occasionally, until soft, 5 to 7 minutes.
Step 4
Meanwhile, heat another pan over medium heat. Cook spinach until heated through, about 5 minutes. Drain.
Step 5
Whisk eggs, milk, salt, and pepper together in a large bowl until well combined and foamy. Add the onions, spinach, tomatoes, and feta cheese and stir to combine. Pour egg mixture into the prepared dish.
