Preheat your oven to 350°F (175°C) to ensure even cooking.
Brush your 9x13 inch baking dish with olive oil or spray it with nonstick spray.
In a large mixing bowl, crack the 10 eggs and whisk them until fully combined. Add in the Spike Seasoning, salt, and freshly ground black pepper to taste. Mix well.
Fold in the green bell pepper strips, halved cherry tomatoes, and crumbled feta cheese into the egg mixture. If using dried oregano, sprinkle it in now.
Carefully pour the egg and vegetable mixture into the prepared baking dish, ensuring it is evenly distributed.
Place the baking dish in the preheated oven and bake for about 30-35 minutes or until the eggs are set and the top is slightly golden.
Once baked, remove from the oven and let cool for a few minutes. Cut into squares and serve warm.
