Step 1

Position a rack in the middle of the oven and preheat to 375 degrees.

Step 2

Spread the broccoli rabe and grapes on a large rimmed baking sheet. Drizzle with the oil and sprinkle with the salt, then use your clean hands to toss and coat evenly; make sure they are arranged in a single layer. It will look like there is too much broccoli rabe on the baking sheet, but it will cook down and shrink. Arrange the sausages on top, with plenty of room between them.

Step 3

Roast for about 30 minutes, turning the sausages over and giving the broccoli rabe and grapes a stir halfway through, or until the broccoli rabe is tender, the grapes are nearly jammy and the sausages are cooked through and browned.

Step 4

Serve hot, straight from the baking sheet.
