If you like chilies and cilantro, you may find yourself using this lively salsa on everything—over pasta, atop pizza, in eggs, on sandwiches, stirred into soups, spread over grilled vegetables, drizzled over couscous or rice, and so forth. If you combine everything but wait to add the lime juice or vinegar until just before using the salsa, you can keep it, refrigerated, for several days. Vary the flavors, if you like, by including other spices, such as ground cumin and paprika.
