Preheat a grill for cooking over medium-high heat. In a large bowl, combine the olive oil, dried parsley, garlic powder and vinegar. Mix well to combine and set the marinade aside while you prepare the vegetables.
Trim the ends from the zucchini and slice lengthwise 1/4- to 1/2-inch thick (if the zucchini are more than 4 to 5 inches in length, cut in half before slicing). Add the vegetables to the marinade and toss well to coat. Set aside for 10 minutes to allow flavors to meld.
Remove the zucchini from the marinade and sprinkle with salt and pepper. Grill the zucchini until just tender, about 2 minutes per side. Arrange on a platter and garnish with the Brown Sugar-Bourbon Pumpkin Seeds, cilantro and queso fresco, if using.
