Creating your fresh tomato salsa is straightforward and rewarding. Follow these steps for a delicious result:

1. Prep the Ingredients: Start by washing all your vegetables thoroughly.
2. Dice the Tomatoes: Cut the tomatoes into small, even pieces. Place them in a mixing bowl.
3. Chop the Onion: Finely chop the red onion and add it to the bowl with the tomatoes.
4. Mince the Jalapeños: Carefully remove the seeds from the jalapeños to control the heat. Mince them and add them to the mixture.
5. Add Cilantro: Chop the fresh cilantro and fold it into the salsa for a burst of flavor.
6. Add Lime Juice: Squeeze the juice of two limes over the mixture. This not only adds flavor but also helps preserve the freshness of the ingredients.
7. Season: Add salt to taste. If using cumin, sprinkle it in now and mix well.
8. Combine: Stir all the ingredients together until evenly mixed.
9. Chill: If time allows, cover the bowl and let the salsa chill in the refrigerator for at least 15 minutes to allow the flavors to meld.
10. Serve: Enjoy your fresh tomato salsa as a dip, topping, or side!
