The house we have here on Maui has a couple of fruit bearing trees on it and one of them happens to be an avocado tree. My wife really likes the guacamole that I make so she is extremely happy.
My recipe, which was given to me by a friend (thank you Bridget!) is;
Avocado of course, mashed with a fork so it is creamy but with some small chunks left in. To that you add finely chopped onion (I prefer red onion but white or yellow will work), jalapeno, tomato, cilantro, a little salt and some fresh squeezed lime juice. Finely chopping the onion, cilantro, tomato and jalapeno makes all the difference in the taste so don't get lazy with your knife skills.
Add a bag of tortilla chips with a cold beer or margarita and you're good to go!
