- 3 tbsp sesame oil
- 1 tbsp sweet white miso paste
- 1 tsp dulse granules
- 1/2 tsp chili powder
Asian Slaw
- 2 cups coleslaw veggies

- 2 tbsp rice vinegar
- 2 tbsp soy sauce
- 2 tsp pure sesame oil
- 1/2 tsp ground ginger
- 1/2 tsp kosher salt
Wasabi Mayo
- 1 tsp wasabi powder
- 1 tsp warm water
- 1/4 cup vegan mayonnaise
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!
