Preheat grill to medium-high heat.

Lightly brush the watermelon slices with olive oil.

Once the grill is hot, place the watermelon on the grill.

Cook 2-3 minutes. Flip and cook for another 2-3 minutes.

Remove from grill and allow to cool.

Cut watermelon into cubes and divide evenly between two bowls.

Squeeze half of a lime onto each bowl and season with a little sea salt and cayenne pepper, if desired.

Sprinkle crumbled goat cheese on top of each bowl and finish with fresh mint.

Serve immediately or chill before serving.
