Tomatoes are used in a seemingly infinite amount of recipes and often need to be diced. Dicing tomatoes is a quick, simple process anyone can master with some practice. Both Roma and regular tomatoes can be diced and then added to salads, soups, casseroles, and other dishes.

How do you dice a tomato?

  1. Use a small spoon to remove the stem and core from the tomato.
  2. Place your knife at the bottom of the tomato and cut it evenly in half.
  3. Make a series of vertical cuts to slice each half into thin strips.
  4. Cut horizontally across each strip to dice the tomato.
