Holy guacamole!

So as I indicated earlier this week, I had avocados. What do you do when life, er, Trader Joe's gives you avocados? You make guacamole! My friend from Guatemala will go on a 10 minute rant about how the only ingredients in guacamole should be lime juice, avocados and salt. While his guacamole is traditional, I prefer it with the addition of a couple of more ingredients.
Guacamole
Makes about 2 cups
Ingredients:
3 ripe avocados
1/4 cup minced red onion
1/2 diced tomato (I've used chunky salsa instead in a pinch)
1 1/2 tb lime juice (I used the bottled stuff, so start with a little less if you're using the real thing)
1/2 tsp garlic powder
1/2 tsp salt (plus more to taste if you like it saltier)

Directions:
Cut avocados in half lengthwise. Remove and discard the seed. Scoop out the flesh with a spoon into medium bowl. Break up the avocado into smaller pieces with a fork. Add all ingredients except the tomato and mash with fork until almost creamy. I like chunks in my guacamole. Add tomatoes and stir to combine. Refrigerate if not using immediately.
