This simple salsa has been on repeat all summer long. It's a play on a classic pico de gallo, which is a raw salsa traditionally made with tomatoes, onion, Serrano chiles, lime juice and cilantro. I like to use shallots for a milder onion flavor, and let them soak in the lime juice for a while to mellow their bite. Pickled jalapeños replace the traditional raw chiles for a little more acidity and tang. Enjoy it with tacos, quesadillas, chili, or even as a dressing for chicken or fish.
