Cook chorizo over medium-high heat in a skillet
Place cooked chorizo on a paper towel and pour out some of the grease (if desired) leaving some to cook the eggs in.
Break two eggs into a medium heat skillet with chorizo grease and scramble. Add milk if desired to make it more fluffy.
Once cooked place eggs at bottom of a bowl.
Top the eggs with chorizo and layer on the avocado, cheese, tomato, sour cream and cilantro.
Serve immediately while still warm and enjoy your trip to Mexico!
