Creating Grilled Watermelon-Feta Skewers is simple when you follow these steps:

1. Prepare the Watermelon: Cut the watermelon into 1-inch cubes. Alternate between cubing the watermelon and cutting the feta into similar-sized pieces.
2. Soak Skewers: If using wooden skewers, soak them in water for about 30 minutes to prevent burning on the grill.
3. Skewering: Thread the watermelon and feta onto the skewers, alternating between the two to create a colorful pattern.
4. Brush with Olive Oil: Lightly brush the skewers with olive oil, ensuring an even coating to help with grilling and flavor.
5. Add Seasoning: Sprinkle with salt and pepper, adjusting to your taste preference.
6. Preheat the Grill: Heat the grill to medium-high.
7. Grill the Skewers: Place the skewers on the grill for about 5-10 minutes, turning occasionally until grill marks appear and the watermelon is slightly caramelized.
8. Remove and Serve: Once cooked, carefully remove the skewers from the grill. Transfer them to a serving platter and garnish with fresh mint leaves.

These steps will effortlessly guide you through the grilling process, ensuring delicious outcomes every time.
