Combine ingredients: In a large bowl, combine the diced tomatoes, onion, jalapeño, cilantro, lime juice, garlic, cumin, salt, and pepper.

Mix well: Stir the ingredients together until thoroughly combined.

Adjust flavor: Taste the salsa and adjust the seasonings to your preferred taste. Add more lime juice, jalapeño, or salt and pepper as needed.

Chill: Transfer the salsa to an airtight container and refrigerate for at least 2 hours, or overnight, to allow the flavors to meld.

Tips:

For a smoother salsa, roast the tomatoes and jalapeño before dicing them.

To make a chunky salsa, leave some of the tomatoes and onion in larger pieces.

For a spicier salsa, add more jalapeño or use a hotter type of pepper.

Serve the salsa with chips, tacos, or as a topping for grilled chicken or fish.

Enjoy your homemade salsa!
