Toss together, taste, and add more salt if needed.
Enjoy immediately or refrigerate and serve when ready to eat.
Notes
Tomatoes: I used Roma tomatoes as that’s what’s traditionally used, but any ripe red tomatoes will work.
Jalapeño: The spice level of pico de gallo is totally up to you. I used a jalapeño to keep it on the milder side, but you could use a serrano pepper to make it even spicier.
Onion: White onion is what’s traditionally used, but you can also use red or even yellow in a pinch.
Salt: Add salt to taste. Start with a little, then work your way up. You’ll likely need more salt than you think to really bring out the flavors!
Let it marinate: The longer the pico de gallo sits, the longer the flavors have a better opportunity to come together. I recommend letting it marinate in the fridge for at least 30 minutes or up to 1 day before serving. Doing this also helps to cut some of the bite and heat from the white onion and garlic.
