Preheat your oven to 350°F (175°C) to ensure even cooking.
In a large mixing bowl, whisk together the 14 eggs until well beaten. Add drained diced tomatoes and diced green chiles, mixing until combined.
Sprinkle in salt, fresh-ground black pepper, and Spike Seasoning. Stir until evenly distributed.
Fold in grated Monterey Jack and Mozzarella cheeses, ensuring they are well mixed.
Add thinly sliced green onions and give it one last stir to combine.
Pour the mixture into a greased 9x13 inch baking dish and spread evenly. Bake for 30-35 minutes until the center is set and the top is lightly golden.
Remove from the oven, let cool for a few minutes, then slice and serve warm.
