Preheat the smoker to 225F. As the smoker preheats, prep the ingredients. Quarter the tomatoes, cut the onion in half, slice the jalapeño in half, peel the garlic, then toss with olive oil in a disposable aluminum pan.

Place the pan in the smoker and close the lid. Smoke for 90 minutes. Remove from smoker and let cool.

Transfer the smoked ingredients along with the fresh cilantro, lime juice, and salt to a food processor or blender. Pulse until salsa reaches desired consistency.

Enjoy salsa immediately or transfer to an airtight container and let chill in the refrigerator until ready to serve.
