Creating Watermelon Feta Salad is straightforward when you follow these simple steps:

1. Prepare Watermelon: Start by cutting the watermelon into bite-sized cubes. Place them in a large mixing bowl.
2. Add Feta: Sprinkle the crumbled feta cheese over the watermelon cubes.
3. Chop Mint: Finely chop the fresh mint leaves and add them to the mixing bowl.
4. Diced Onion (Optional): If desired, add the diced red onion for an extra crunch and flavor.
5. Dress the Salad: In a small bowl, whisk together the olive oil and balsamic vinegar. Pour over the watermelon, feta, and mint mixture.
6. Season: Sprinkle salt and pepper to taste. Be careful not to add too much salt, as the feta is already salty.
7. Toss Gently: Using a large spoon, gently toss the salad until all ingredients are well combined.
8. Chill (Optional): If you have time, let the salad sit in the refrigerator for about 10 minutes before serving. This allows flavors to meld.
9. Serve: Enjoy the salad cold or at room temperature for the best taste.

These steps make the preparation of this incredible salad a breeze!
