Preheat oven to 350°F. Grease a 12-cup muffin pan or spray with nonstick cooking spray.
In a medium bowl, whisk together the eggs, milk, hot sauce, salt, and pepper until well combined.
6 large eggs, ½ cup whole milk, 2 drops hot sauce, ¼ teaspoon salt, ⅛ teaspoon pepper
Stir in the zucchini or spinach, roasted red peppers, red onion, and cheese.
1 cup zucchini or fresh spinach, ¼ cup roasted red peppers, 2 tablespoons red onion, 1 cup shredded Cheddar cheese
Divide the mixture evenly between the muffin cups. The muffin cups will be nearly full.
Bake for 20-22 minutes or until the eggs are fully set.
Allow the egg muffins to cool in the pan for 3-5 minutes.
Run a butter knife around the edges to loosen and carefully remove the muffins.
Serve warm.
