Preheat oven to 450 degrees F. Lightly oil a baking sheet or coat with nonstick spray.
Thread shrimp and lemon halves onto skewers. Place skewers onto the prepared baking sheet. Place into oven and roast just until pink, firm and cooked through, about 5-7 minutes.*
Melt butter in a medium skillet over medium high heat. Stir in lemon juice, garlic, oregano, thyme and basil until fragrant, about 2 minutes; season with salt and pepper, to taste.
Serve shrimp skewers immediately, brushed with butter mixture and garnished with parsley, if desired.
