Chop the tomatoes into small, uniform pieces and transfer them to a large mixing bowl, allowing their juices to begin mingling.
Add the finely chopped cilantro, minced red onion, and minced garlic to the bowl with the tomatoes.
Seed and dice the jalapeño pepper finely, then sprinkle it into the mixture, adjusting the amount based on your spice preference.
Squeeze the juice of two fresh limes into the bowl, then stir everything together with a wooden spoon or spatula until well combined.
Season with salt and freshly ground black pepper, then give the salsa one last gentle stir to distribute the flavors evenly.
Let the salsa sit for about 5 minutes at room temperature to allow the flavors to meld and the mixture to slightly thicken.
Give the salsa a final stir, taste, and adjust seasoning if needed, then serve immediately with chips, tacos, or grilled meats.
