In a large microwave-safe bowl, combine potatoes, 1 tablespoon oil and salt. Microwave, covered, on high for 6-8 minutes or until tender, stirring every 2 minutes.
Meanwhile, in a large skillet, cook sausage over medium heat 6-8 minutes or until no longer pink, breaking into crumbles; remove with a slotted spoon.
In same skillet, heat remaining oil over medium-low heat. Add apple and carrot; cook, covered, 5-7 minutes or until carrot is just tender, stirring occasionally. Return sausage to pan. Stir in sweet potatoes and seasonings; cook, covered, 10-12 minutes or until carrot is tender.
