Preheat oven to 425°F. Toss the vegetables in oil to generously coat. Spread on a baking sheet so they’re not touching and sprinkle with Sakari Botanicals salt and fresh sage. Roast, shaking the pan often, until vegetables are tender and begin to brown, about 30-40 minutes.
In a small bowl, mix maple syrup, maple vinegar and mustard. Brush over the roasted vegetables. Return to the oven to roast another 7-10 minutes. Remove and serve warm.
