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, and 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.
Store in an airtight container in the fridge for 48-72 hours. You can also put all the ingredients into a food processor or blender for more of a ‘restaurant style’ salsa, and it’s great for canning purposes this way too.
