Step 1

Give the tomatoes, jalapeno, and cilantro a good rinse.  Peel the onion and de-stem the tomatoes and jalapeno.  I usually twist off and discard the bottom, thicker portions of the cilantro stems, but keep the upper portion of the stems that hold the leaves together.

Step 2

Finely chop the 2 tomatoes, 1/2 onion, and jalapeno into 1/4" sized chunks.  Finely dice the cilantro.  For a milder version you can start by using only 1/2 of the jalapeno and adding more incrementally if you want more heat.

Step 3

Combine the tomato, onion, jalapeno and cilantro in a mixing bowl.  Add a heaping 1/4 teaspoon of salt and the juice of a single lime.  Mix together well and taste for seasoning.  Add additional salt and lime if necessary (I added more salt to this batch).

Step 4

Serve immediately or store in an airtight container in the fridge.
