Cut the tomato and onion into very small dice. Wash the cilantro and shake dry. Roughly chop the cilantro.
Combine the tomato, onion, and cilantro in a bowl.
Squeeze the juice from half of the lime over the mixture and sprinkle it with salt.
Give everything a good stir and then adjust the lime and sea salt to your liking. Serve as a topping with organic corn chips or on baked chicken breasts!
