Dice the tomatoes into small, even pieces and place them in a mixing bowl, listening for a gentle sizzle as they settle.
Finely chop the red onion and sprinkle it over the tomatoes, watching as the layers of color mix and create a textured mosaic.
Roughly chop the fresh herbs—basil, cilantro, and oregano—and add them to the bowl, noting the vibrant green flakes contrasting with the red and white ingredients.
Cut the lime in half and squeeze the juice directly over the mixture, listening for the citrus burst and watching the juice distribute evenly.
Sprinkle in the freshly ground black pepper and gently toss everything together with a spoon, observing the salsa come together with bright colors and fresh aromas.
Let the salsa sit for 5 minutes to allow the flavors to meld, while noticing the fresh herbs releasing fragrance and the mixture slightly softening.
Give the salsa a final stir, then taste and adjust seasoning if needed, noting the lively freshness and balanced acidity.
