For the applesauce: Preheat the oven to 375 degrees F.
Peel the apples, then thinly slice around the core. Place in a microwave-safe bowl and cover with plastic wrap. Microwave until the apples are tender, about 5 minutes. Place in a blender with the butter and puree. Set aside.
For the sausage balls: Grease a rimmed baking sheet with the oil. Combine the sausage, cheese, pancake mix, chives, a big pinch of salt and a few grinds of black pepper in a large bowl and mix well. Roll into 1 1/2-inch balls (about the size of a Ping-Pong ball). Place on the prepared baking sheet in an even layer, leaving 1 inch between balls. Bake until cooked through and browned, 20 to 25 minutes. Serve with the applesauce.
