Give the watermelon a good wash under cold water to remove any dirt or debris.
1 watermelon
Cut watermelon in half horizontally (around the equator).
Place one half face down on the cutting board. Make 1 inch vertical cuts across the watermelon.
Rotate the watermelon or cutting board 90 degrees and repeat the 1 inch vertical cuts to create a grid pattern.
Repeat with the second half of watermelon. Serve!
