Drizzle the ingredients with the olive oil, toss to coat and spread evenly over the baking sheet. Distribute the sausage over the sheet pan and sprinkle with salt.
Roast for 30-35 minutes or until vegetables are tender. If additional color is wanted, broil for 1-2 minutes or until golden.
Meanwhile melt the butter in a small sauce pan and add the vinegar. Cook for 2 minutes over medium heat until bubbles appear and mixture starts to reduce.
Remove the sheet pan from the oven and drizzle with the butter/vinegar mixture.
