Cut avacaodoes in half length-wise.  Use a sharp knife and rap the nut until the knife embeds into the nut firmly.  Use a twisting motion and the nut will come out easily.  They'll think you lived in Mexico with that trick.  Use a tablespoon and scoop out the pulp into a large mixing bowl.

Use a fork to mash the pulp.  You can make it as chunky or smooth as you desire.

Add onion, jalapenos, garlic powder, lemon juice, tabasco.  Mix well.  Add salt and pepper and mix well again.

Refrigerate for one hour.
