Watermelon "Tuna" Tacos (Vegan)

April 28, 2021
A couple of years ago, poke bowls became super popular, and it wasn’t long before a vegan version followed shortly behind. By cutting watermelon up into bite-sized chunks and leaving them to marinate, the fruit is transformed into a deceivingly realistic tasting “tuna.” Because watermelon is pretty bland to begin with, it easily absorbs and takes on the flavor of whatever you soak it in.

Instead of making a poke bowl, I decided to use the “tuna” to make fish tacos. These are stuffed full of fresh veggies that would generally come in a poke bowl and make a refreshing lunch on a warm day. I didn’t feel the need to use a dressing on this because it was so flavorful and a squeeze of lime did the job but if you would prefer to use one, I recommend a Sriracha mayo or cilantro vinaigrette.
