Add the canned tomatoes, onion, garlic cloves, jalapeños, cilantro, lime juice, salt to the jar of a blender or bowl of a large food processor. Blend or process until the ingredients are broken down and pureed to your desired smoothness and consistency. Adjust seasonings to taste, adding more salt if necessary.

Transfer to a sealed container and chill in the refrigerator for at least one hour before serving, to allow the flavors to blend.
