Preheat oven to 400 degrees. Line a baking sheet with tin foil then coat with cooking spray.
Place the veggies on the prepared baking sheet. Drizzle with the olive oil then season with sea salt and freshly cracked pepper, to taste; toss to coat evenly.
Place into the oven and roast for 13 minutes. Remove from the oven and toss with minced garlic. Place back into the oven and roast for 2 minutes or until done. Remove from the oven and serve immediately. Enjoy.
