In a medium bowl, combine White Wine, olive oil, garlic, Kosher salt and freshly ground black pepper. Whisk well.
Add shrimp, tossing to combine. Cover and marinate for 30 minutes up to 8 hours. Do not over marinate, as this can lead to over salted food or the shrimp having a tough texture.
If using wooden skewers, allow to sit in water for 30 minutes prior to threading.
Alternate threading shrimp, yellow squash, red onion and grape tomatoes onto each skewer, leaving ample room at both the top and bottom for easy handling.
Heat grill to medium-high heat. Clean and oil grates.
Place shrimp skewers over indirect heat on grill. Allow to cook for approximately 10-12 minutes, turning occasionally.
When cooked, remove and top with fresh lemon juice. You can top with minced parsley or Maldon sea salt for garish, if desired.
