Finely dice the cherry tomatoes and red onion. Thinly slice the chilies, finely chop the cilantro, and mince the garlic if using.


Add the tomatoes, onion, chilies, cilantro, oregano, lime juice, garlic, sugar if using, and salt to a mixing bowl. Stir well until evenly combined.
Let the pico de gallo rest for 20 to 30 minutes in the refrigerator so the flavors can blend. Stir again before serving, then serve chilled or at room temperature with your favorite Mexican dishes.
