In a medium bowl, combine carrots, oil, salt, and garlic powder. Toss well to coat.
Heat a grill to low heat.
Add the carrots to the grill and close the lid. Cook for 25 to 30 minutes or until fork tender, turning frequently to prevent burning.
Transfer the carrots to a serving plate and drizzle with additional olive oil. Season with salt and pepper and garnish with fresh herbs if using.
Notes
Use 1 tablespoon total of fresh herbs. Dill, parsley, basil, or a combination work well in this recipe.These carrots will keep in an airtight container in the refrigerator for up to 5 days and in the freezer for up to 2 months.
