Tips & Variations
- For extra smoky flavor, use fire-roasted green chiles or add a pinch of smoked paprika to the egg mixture.
- Try substituting pepper jack cheese for a spicier kick.
- To make it vegetarian, use vegetable broth or milk alternatives if desired, but keep eggs for structure.
- Add cooked and crumbled chorizo or cooked ground beef between the layers for a meaty version.

Instructions
- Preheat Your Equipment: Preheat your oven to 375°F (190°C). Lightly grease your baking dish with butter or cooking spray to prevent sticking and promote browning.
