Roma Tomato, Watermelon, and Nori Sesame Salad

Another Costco Business special. I bought a 25 lb case of Roma tomatoes and a pound of cilantro and then adapted this recipe to help use them up.


  • Dressing
    • 2 tablespoons extra virgin olive oil
    • 2 tablespoons rice vinegar
    • 2 teaspoons sugar
    • 2 teaspoons reduced sodium soy sauce
    • 1.5 teaspoons oyster sauce
    • 3 tablespoons julienned fresh ginger
    • 1 clove garlic, minced
  • Nori sesame salt
    • 2 nori sheets
    • 1.5 tablespoons toasted sesame seeds
    • 0.25 teaspoons kosher salt
  • Salad
    • 2 lbs Roma tomatoes (cut into chunks)
    • 1 lb watermelon (cubed, roughly the same size as the tomato chunks)
    • 3 scallions (chopped)
    • 1 cup cilantro (coarsely chopped)


  • Whisk the olive oil, vinegar, sugar, soy sauce, and oyster sauce together. Stir in the ginger and garlic, set aside.
  • Tear nori sheets into smaller pieces and pulse in a small food processor to turn it into a coarse powder. Stir in toasted sesame seeds and salt.
  • Combine tomatoes, watermelon, scallions, and cilantro in a bowl. Pour dressing over salad and stir to combine.
  • Just before serving, top with the nori sesame salt.


  • This recipe is crammed full of flavor. Olive oil, rice vinegar, soy sauce, ginger, garlic, oyster sauce, nori, sesame, tomato, cilantro, scallion – each ingredient packs a punch. They all work together and it tastes great, but think of this more like a tasting menu dish – have a small amount and leave yourself wanting more.
  • The original recipe calls for plums instead of watermelon. Substitute 5 large plums for the watermelon. It also tastes good, shown below.
