Guacamole is so so good, and as convenient as store bought is, nothing beats homemade! And it really is quite simple. I've had this  recipe for years and its good everytime. 

2 whole ripe avocados 
1 tomato
Quarter of a white onion
Quarter of a bunch of cilantro chopped finely 
2-3 gloves garlic, or garlic paste
Half a lime

1. Finely chop the tomato, cilantro & onion into small pieces. 
2. Squish avocados until completely mushed up 
3. Mix all together, add the garlic paste and squeeze in lime. Serve with chips or top off a burger or taco :)
