Add the biscuit mix and sausage to a large mixing bowl. Mix them together until evenly incorporated.

Add the cheese to the mixture, and mix again until all the cheese is also evenly incorporated.

Line two large baking sheets with parchment paper. Roll the sausage mixture into roughly 1 ½ inch balls.

Place the balls on the parchment, roughly spacing them out about ½ inch apart from each other. Repeat until all the mixture's been rolled into balls & added to the prepared baking sheets.

Bake the sausage balls at 350 degrees for 25 minutes.

Cover a clean surface with a double layer of paper towels. Transfer the cooked, still hot sausage balls from the baking sheets to the paper towels to drain off/soak up any excess grease.

Serve when still warm, but cool to the touch.
