  • 1 small watermelon (cut into bite-size triangles)
  • 2 Tbsp finely sliced avocado
  • 2 Tbsp pickled ginger
  • 1/4 medium red onion (very thinly sliced)
  • 1-2 tsp sesame seeds


  • 1 Tbsp sesame oil
  • 2-3 Tbsp tamari (if gluten-free, ensure gluten-free)
  • 1/4 tsp wasabi (optional)


  1. Cut watermelon into bite-sized triangles and set on a paper towel or clean towel to draw out some of the moisture.
  2. In the meantime, whisk together the glaze ingredients. Set aside.
  3. To assemble, transfer watermelon to serving plate(s) and brush the tops with the glaze. Then top with avocado, red onion, pickled ginger, and sesame seeds.
  4. Enjoy immediately! Best when fresh, though can be refrigerated up to 24 hours in advance.
