Homemade Guacamole From Scratch

This one's for my wonderful mother-in-law, who taught me to love guacamole, and at whose home I will be staying this weekend (yes, we will be making this!)

Guacamole
2 avocados
1 large bunch of cilantro
1 Tbsp lemon or lime juice
1/2 tsp onion powder
1/4 tsp garlic powder
1/4 tsp salt
one medium seeded and chopped tomato (optional; I usually leave this out)

Cut the avocados in half, pop out the seeds, scoop out the yummy green part, and discard the skins (you're putting all of those veggie scraps in your compost, right? Or at least giving them to your chickens?)
Mix that yummy green stuff and the spices all together and puree (you can do this with a fork, or for a finer texture use a stick blender)
Serve with tortilla chips, or add to your favorite Mexican recipe.
