Step 1: Preheat your oven to 350°F (175°C). This ensures that your muffins bake evenly and come out fluffy.
Step 2: Lightly grease your muffin tin with non-stick cooking spray or line it with muffin liners for easy cleanup.
Step 3: In a large mixing bowl, crack the 15 eggs and whisk them thoroughly until they are well combined. You want to incorporate air into the eggs to make them light and fluffy.
Step 4: To the whisked eggs, add the drained green chiles, Mexican blend cheese, Spike seasoning, salt, and fresh ground black pepper. If you're using green onions, stir them in as well. Mix everything until well combined.
Step 5: Pour the egg mixture evenly into the prepared muffin tin, filling each cup about 3/4 of the way full to allow room for rising.
Step 6: Place the muffin tin in the preheated oven and bake for about 20-25 minutes, or until the muffins are puffed up and a toothpick inserted in the center comes out clean.
Step 7: Once baked, remove the muffins from the oven and let them cool in the tin for about 5 minutes. Then, carefully remove them and place them on a wire rack to cool completely. Enjoy them warm, or store them for later!
