To dice the peaches, cut each peach in quarters all the way to the pit, then remove slices off of the pit. Dice and add to a large bowl. Prep other ingredients.
Add tomatoes, red onion, jalapeno, lime juice, salt and pepper.
Stir, cover and refrigerate for about 15 minutes, if you have time. Taste and adjust any seasonings, if you wish. For more heat, add chili powder.
Serve with tortilla chips or pile up on top of grilled meats and fish, or spoon over tacos.
Notes
If you want salsa to be more spicy, do not seed the jalapenos.
Store: Refrigerate salsa in an airtight container or Mason jar and it should last for up to 4 days.
Make ahead: If you like a very fresh salsa, you can make it ahead. Add diced ingredients into a bowl without stirring or adding salt until you are just about ready to serve.
