Combine the tomatoes, onions, jalapeno, and cilantro in a large bowl. Add the lime juice and salt and stir. Refrigerate it for at least a couple of hours before serving.

After it’s chilled, give it a taste and add more lime juice and/or salt, if needed. Serve it with chips as an appetizer or use it like you would salsa and spoon it over all the things. It will keep well in the fridge for three to four days.
