Preheat oven to 375°F.
Heat a medium skillet over medium high heat. Add chorizo and onions. Note that oil should not be needed as the chorizo provides the necessary oil. Cook until chorizo and onions are fully cooked.
Season with salt and pepper (if desired). Note that salt might not be needed as the chorizo is usually seasoned. Taste before seasoning. Drain excess oil and evenly distribute chorizo mixture into a muffin tin. Set aside.
In a medium bowl combine the eggs and coconut milk. Whisk until very well combined.
Evenly distribute the egg mixture over the chorizo. If you decide to add extra veggies, this is the time to do so.
Bake for 20 minutes. Enjoy!
