How to Make It
Preheat the oven to 375°. In a very large bowl, toss the yellow peppers with the tomatoes, onions, chiles, garlic, olive oil and vinegar and season with salt and pepper. Scrape the vegetables onto 2 large rimmed baking sheets and roast for 15 minutes, until just softened. Arrange the sausages on the vegetables and roast for 25 to 30 minutes, until the vegetables are lightly browned and an instant-read thermometer inserted into each sausage registers 165°; rotate the pans halfway through roasting. Transfer to a platter, scatter the basil on top and serve.
