Place the diced tomatoes into a strainer, or colander, over a large bowl. Let ‘drain’ for about 30 minutes. Reserve the juice for another use, if desired. In a large bowl, combine the tomatoes, onion, jalapenos, & cilantro. Squeeze the juice of 1 lime on top, and stir. Cover, and let sit in the fridge for 30 minutes for flavors to marry.
