Preheat oven to 375 F. In a large bowl, toss all the vegetables with the olive oil, rosemary, garlic, sea salt and pepper. Arrange the vegetables in a large roasting pan that has been lightly coated with some extra virgin olive oil. Cover tightly with aluminum foil and bake for 35 minutes. Remove the foil and turn the vegetables over with a large spoon. Increase oven temperature to 425 F and roast uncovered for 20 to 25 minutes until potatoes are cooked and carrots are cooked. Make sure that edges don’t burn. Makes 6 servings.
