In a medium bowl, mix together all of the salsa ingredients: peaches, bell pepper, tomato, jalapeno, red onion, cilantro, lime zest (zest it directly over the bowl), lime juice, and salt.
Stir to combine, then taste and add more salt as desired. If time allows, chill 30 minutes prior to serving, or enjoy right away.
Notes
TO STORE: Refrigerate leftover peach salsa in an airtight container for up to 2 days.
