Sautéed Brussels sprouts with curly kale, bacon and chestnuts

1.For roasted chestnuts, preheat oven to 190C. Heat butter and oil in a large, ovenproof frying pan over medium-high heat, add chestnuts and stir frequently until starting to brown (2-3 minutes). Transfer to oven and roast until chestnuts are golden on the base (12-18 minutes).

2.Meanwhile, heat a large frying pan over medium-high heat, add half the oil and the bacon, in batches, and turn occasionally until crisp and golden (3-5 minutes). Transfer bacon to a warmed plate, set aside and keep warm.

3.Reduce heat to medium, add remaining oil, and onion and garlic to pan and cook until onion is tender (5-10 minutes). Add Brussels sprouts and cook for 1-2 minutes, then add kale and cook, tossing occasionally, until wilted (1-2 minutes). Add chicken stock and stir occasionally until sprouts are tender (2-4 minutes), then add chestnuts, toss to combine and serve hot with bacon.
