I have been using the same Guacamole recipe for soooo long I can't even remember where it came from. This is simple and tasty way to make Guacamole, and I will let you in on my secret!
If you buy an Avocado and place it in your refrigerator it will stay good for a very very long time, weeks even, and ripen very slowly!
2 medium Avocados, seeded, peeled and diced
Mash everything together in a bowl, using a fork (except tomato)
Add the diced tomato to finished Guacamole and mix well
