Guacamole!! Healthier than mayo and goes on just about anything. I made this the night before our burger night to use on a salsa burger (recipe to follow), but we use it for much more.
Isn't it pretty (on a Trader Joes Flax Seed chip):
3 avocados (mashed)
1 small red onion (chopped)
1 bunch cilantro leaves (chopped)
1 jalapeno pepper (or whichever type you prefer) (chopped)
hot sauce to taste
pepper to taste
juice of 2 limes
Combine all ingredients and mash with potato masher.
