Wash and finely dice the Roma tomatoes, transferring them to a large glass mixing bowl.

Finely chop the white onion and mince the jalapenos, removing seeds if a milder flavor is preferred, then add them to the bowl.

Roughly chop the cilantro and add it to the vegetable mixture.

Squeeze the fresh citrus juice over the top and sprinkle with kosher salt.

Stir all ingredients gently to combine, cover the bowl, and let it rest in the refrigerator for 15 minutes before serving with tortilla chips.
