Cut open, pit and scoop out two avocados. Mash the avocado with a fork until smooth.
Finely chop the red onion and tomato. I actually use a Tupperware chopper like this. It helps it get finely chopped up. Squeeze in juice of the lime. I like mine very lime-y so maybe start at half a lime first.
Add garlic powder and salt and pepper to your taste.
Enjoy and FIESTA!
