Place eight baking cups inside your muffin tin and set aside.
In a large bowl, beat the eggs.
Mix in the cheese, salt, and chopped vegetables.
Divide the egg mixture evenly between the baking cups.
Bake in the preheated oven for 15-20 minutes, or until a toothpick comes out clean.
Serve warm and enjoy!
Notes
Nutrition values are estimated based on bell pepper, onion, jalapeno and zucchini, but you can use any combination of veggies you like. Although they're best served fresh, leftovers can be stored in an airtight container in the fridge or freezer and then reheated.
