Preheat oven to 400 degrees Fahrenheit and line a baking sheet with parchment paper.
Prepare all vegetables as instructed, aiming for similar sized pieces. Add them to a large bowl or Ziploc freezer bag.
Drizzle the olive oil into the bowl or bag and sprinkle the vegetables with oregano/rosemary/basil, garlic powder, salt and pepper. Toss the vegetables together until they are evenly coated with oil and seasonings.
Spread the vegetables out evenly on the lined baking sheet and cook for 20-25 minutes or until they are fork-tender, stirring them at the half-way cooking point.
Serve alongside your Thanksgiving meal, paired with meat or fish, as part of a nourishing bowl or tossed into a warm salad. Enjoy!
