Chop the tomatoes into small, even pieces, ensuring to remove any excess watery pulp for a better texture.
Add the finely chopped red onion to the bowl with the tomatoes, mixing them together to combine flavors and textures.
Stir in the chopped fresh cilantro, sprinkling it evenly over the mixture for a burst of herbal aroma.
Squeeze fresh lime juice over the mixture, tossing gently to incorporate the citrus flavor throughout the salsa.
Season with salt and black pepper, stirring to distribute evenly and enhance the overall flavor.
Let the salsa sit for a few minutes to meld the flavors, then give it a final stir before serving.
