Recipe

Step 1
In a large airtight container, add watermelon, seaweed, tamari, white rice vinegar and sesame oil. Put on the lid and shake gently to distribute the seasonings.
Step 2
Place in the fridge for at least 2 hours and up to 24 hours to marinate.
Step 3
After marinating, preheat oven to 250ºF and line a baking sheet with parchment paper.
Step 4
Place all the cubes on the parchment paper. Reserve the sauce to use in another recipe such as an Asian sauté or a pad Thai.
Step 5
Bake for 2 hours, flipping the cubes halfway through.
Step 6
After 2 hours, increase oven temperature to 350ºF and bake for 5 more minutes, until slightly charred.
Step 7
Transfer into an airtight container, close and place in the fridge until cold.
Step 8
Once cold, and right before serving, mix vegan mayo and sriracha together and add into the container with your watermelon. Toss to coat.
Step 9
Serve immediately in vegan sushi, in my Spicy Tuna Poke Bowl or even as a garnish on an avocado toast.

Common Questions & Swaps

Can I use a watermelon with seeds? Yes, of course, you will have to remove the seeds though before baking it.
Can I swap tamari with soy sauce? Yes absolutely!
Can I double the recipe? Yes you can for the amount of watermelon, but I would not double the amount of tamari, seaweed, vinegar or sesame oil. I would only multiply the measurements for those by 1 1/2. So for example, if you want to double the amount of watermelon from 700 grams to 1,400 grams, increase the amount of tamari to 6 tablespoons instead of 8.
Do I have to serve this with a spicy vegan mayo? Absolutely not. You can keep it as is; I just like the spicy mayo because it adds a level of creaminess that I personally enjoy.
