The combination of harissa, honey, lemon and cumin works incredibly well with butternut squash. Everything gets tossed together in the same pan and roasted until the squash is beautifully glazed.
Preheat the oven to 450˚ F. Put the squash in a foil-lined 9-by-13-inch baking dish and toss with the harissa, honey, olive oil, lemon, garlic, cumin and 1 teaspoon salt. Roast, tossing halfway through, until the squash is caramelized and tender, 50 to 60 minutes.
Drizzle the squash with the vinegar and top with mint.
