This bold and beautiful grilled watermelon recipe features a kick of heat, balanced with bright lime and salty cotija cheese. With a bit of cilantro for a pop of freshness and color, this summery side dish is ready for your next cookout. For a more dynamic spice experience, we love Tajin seasoning—which can be found at most grocery stores and pairs exceptionally well with melon. If you have trouble finding it at your local supermarket, try the nearest Mexican market or order it online. You can cut the watermelon away from the rind before or after grilling and chop it into a more composed salad if desired.
