Preheat oven to 425°F (220ºC). Whisk together oil, mustard, vinegar, honey, salt and pepper. Cut squash in half (stem to tip); scoop out seeds. Cut halves crosswise into 1-in. (2.5-cm) thick slices.
Toss together sausages, squash, apple and half the vinaigrette. Arrange in single layer on parchment paper-lined 17 X 12-in. (43 x 30-cm) rimmed baking sheet. Bake 20 min. turning once.
Toss kale with remaining dressing. Arrange on top of ingredients on baking sheet and continue to bake 8 to 10 min. until kale is cooked with crisped edges, sausage is cooked through and squash is tender. Sprinkle with cilantro before serving.
Add any leftovers to soups or stuffings.
