Ingredients
 

Watermelon Tuna Steaks

  • 2 watermelon steaks (Cut steaks of watermelon that are about the size of the palm of your hand and about 3/4 inch thick.)
  • 1/4 cup soy sauce
  • 1 tbsp rice vinegar
  • 3 tbsp sesame oil
  • 1 tbsp sweet white miso paste
  • 1 tsp dulse granules
  • 1/2 tsp chili powder

Asian Slaw

Wasabi Mayo

You Will Also Need

  • 2 whole wheat buns, lightly toasted
  • 2-4 tbsps sushi ginger
  • 1/2 of an avocado
  • *Suggestion: serve burgers with sweet potato fries

Instructions
 

Watermelon Tuna Steaks

  • Add all ingredients (except for the watermelon) to a small mixing bowl and stir until well combined. Place the watermelon steaks and marinade in a container, making sure the steaks are entirely submerged/coated in the marinade.
  • Marinate them in the refrigerator for 24 hours.
  • Preheat the oven to 275 degrees Fahrenheit.
  • Line a large sheet pan with a piece of parchment paper.
  • Drain and shake off the excess marinade from the watermelon. I like to also lightly dab the watermelon with a piece of paper towel to prevent the marinade from burning in the oven. Then, place them on the prepared baking sheet.
  • Bake them on the middle oven rack for 1 hour, flipping them halfway through.
  • Allow the watermelon tuna steaks to completely cool down at room temperature before assembling the burgers.

Asian Slaw

  • Add all ingredients (except for the coleslaw veggies) to a mixing bowl and whisk until well combined. Then, toss in the veggies and stir until evenly combined.
  • Let the slaw marinate for 20 minutes.

Wasabi Mayo

  • Add the wasabi powder and water to a small bowl and stir until a paste has formed. Let this rest for 5 minutes to activate the flavor.
  • Add the mayonnaise and stir until evenly combined.

How to Assemble a Burger

  • Lightly toast a bun. Spread roughly one tablespoon of wasabi mayo on both slices. Top the bottom bun with half of the Asian slaw, followed by one watermelon tuna steak, 1/4 of a thinly sliced avocado seasoned with a tiny pinch of salt, one to two tablespoons sushi ginger, and finish with the top bun!
