• Preheat your oven to 400 degrees. Line rimmed baking sheet with parchment paper and set aside. 
• In a skillet, over medium to medium high heat, cook bacon until crisp and onions until tender.  Remove to drain on paper towel.  Set aside.  
• Remove casings from sausages and dice meat.  
• In a large bowl combine flour, baking powder, salt, and pepper.  Stir with a whisk until blended.  Add butter and using a fork or your fingers mix until mixture resembles coarse meal, or a pile of crumbs.  Add uncooked sausage, cooked bacon and onions, and cheddar and stir until blended.  Add buttermilk and stir until combined. 
• Work with wet hands, roll dough into bite sides balls. I get between 18 and 25 sausage balls. Place on your prepared sheet, as evenly spaced as possible.  Bake until a golden brown color, 20 to 26 minutes.  Rotate the baking sheet halfway through baking if your oven has a hot spot!  Transfer cooked sausage balls to a rack to cool if desired.  Serve warm with dips such as ketchup, sweet and sour sauce, ranch dressing, a sunny side up egg or whatever your heart desires!

Air Fryer

• You can also cook in a preheated 350 degree air fryer in a basket coated in cooking spray for 13 to 16 minutes, depending on their size.
