In a large bowl, whisk together the eggs, salt, and pepper until fully blended.

Stir in the vegetables, mozzarella, and green onions.

Lightly spray silicone muffin cups with nonstick spray and place them in your air fryer basket.

Fill each cup about ¾ full with the egg mixture.

Air fry at 300°F for 12–14 minutes, or until puffed and set in the center.

Let cool slightly before removing from cups. Serve warm or refrigerate for later.

Note: You may need to cook in two batches depending on the size of your air fryer basket.
