Hidden Veggie Spaghetti Sauce is loaded with simple, everyday vegetables hidden in plain sight. This tomato-ey, hearty vegetarian spaghetti sauce is from our easy vegan recipe collection made for stove or Instant Pot...also made for family dinners.
Hidden Veggie Spaghetti Sauce is a delicious, meatless spaghetti sauce with everyday vegetables like mushrooms, carrots, and celery and includes Instant Pot and stove instructions.
