Finely dice the tomatoes, ensuring to remove excess seeds to prevent the salsa from becoming watery. This will help maintain a thicker consistency.

Chop the red onion finely. The smaller the pieces, the more evenly the flavor will distribute throughout the salsa.

Seed and finely chop the jalapeño pepper. Adjust the amount based on your heat preference. Remember to wash your hands after handling jalapeños to avoid irritation.

Chop the fresh cilantro, removing any thick stems. Fresh herbs add a burst of flavor and freshness to the salsa.

Mince the garlic cloves. Fresh garlic provides a robust flavor that enhances the overall taste of the salsa.

In a mixing bowl, combine the diced tomatoes, chopped red onion, jalapeño, cilantro, and minced garlic. Use a spoon to gently mix the ingredients together.

Squeeze the juice of one lime over the mixture. Lime juice not only adds flavor but also helps to preserve the freshness of the ingredients.

Season the salsa with salt, black pepper, and cumin (if using). Stir well to ensure all ingredients are evenly coated with the seasonings.

Taste the salsa and adjust the seasoning as needed. You can add more salt, lime juice, or jalapeño based on your preference.

Let the salsa sit for at least 10 minutes before serving. This resting time allows the flavors to meld together, enhancing the overall taste.

Serve the salsa with tortilla chips, or use it as a topping for tacos, grilled meats, or salads. Enjoy!
