Grilled watermelon shines in this easy, unique salsa recipe! The subtle smokiness and sweet, caramelized watermelon makes this salsa irresistible!
Heat grill {or grill pan} to medium-high heat (about 400°F). Spray or brush the watermelon slices with olive oil to lightly coat. Sprinkle all slices with cayenne pepper and sea salt.
Place watermelon slices on grill, about 1-2 minute per side until light grill marks are visible. Remove and set aside to cool.
When watermelon is cool enough to handle, cut flesh from rind and cut into chunks.
In the bowl of a blender or food processor, add grilled watermelon, shallot, jalapeno, cucumber, tomato, cilantro, and lime juice. Pulse until slightly processed and combined, but still chunky.
Pour into a medium bowl and refrigerate 4 hours or overnight. (You can eat it right away, too, but the flavors develop when you let them sit and get cold.)
