Cut Tomatoes in half and remove mesocarp (soft interior). Dice tomatoes and place on paper towel to remove excess moisture. Dice onions a bit smaller than tomatoes. Remove stem and seeds and finely dice Jalapeño Pepper.
Add Tomatoes, Onions and Jalapeño to mixing bowl. Squeeze Limes over mixture and sprinkle on Kosher Salt. Add Cilantro and Mix through.
Kosher Salt is half as salty as Sea Salt, so make sure you are using Kosher Salt.
