Fry onions with a chopped chilli (maybe more... depends how spicy you like your breakfast). Add salt and pepper, chopped mushroom, and some cubed chorizo.
Scramble a couple of eggs. I added sour cream to make them more creamy. And er... sour.
Fill a couple of flour tortillas with the onion & chorizo, scrambled egg, grated cheese, and guacamole. Roll up and stuff into your face.
This is just possibly my new favourite breakfast. Enjoy!
