Cut off the tough green part of the watermelon rind. Taste the flesh. It should be crispy. If the rind is very tough, you can blanch it in boiling water for a minute. Our rinds were the texture of a cucumber and we didn’t blanch anything. Dice the watermelon rinds.
Peel and slice the onion and grate the garlic. Drizzle the onion and garlic with lemon juice.
Crumble or dice the feta, dice the peeled cucumber, chop the parsley leaves.
Combine all the salad ingredients in a bowl.
To make the dressing whisk together balsamic glaze, olive oil, mustard, and 1 tablespoon of lemon juice until well blended. Taste and add sugar if desired.
Gently stir dressing over salad mix until well coated. Leave the salad in the refrigerator for 2 hours to allow the flavors to meld. Season with salt and pepper. When serving, garnish the salad with lemon slices, pumpkin seeds and parsley. Enjoy!
