-
Preheat oven to 475 degrees.
-
Toss acorn squash, broccolini and red onion on a large rimmed baking sheet with olive oil. Make sure everything is in an even layer and you are using a large enough baking sheet so the vegetables are not crowded.
-
Season with salt, pepper and thyme leaves.
-
Add sausages to top of vegetables and roast until vegetables are tender, about 15-18 minutes.
-
Heat the broiler with the rack about 8-10 inches from the heating element.
-
Sprinkle the gruyere cheese and the sage leaves over the vegetables and broil until the cheese starts to bubble and lightly brown and until the sausages are cooked through, about 3 minutes.
-
Remove from the oven and sprinkle with the cranberries. Serve immediately.
