Open the biscuit can and split each biscuit in half to create 16 thin pieces.

Cut the ham into small pieces and the Swiss cheese into 16 cubes.

Spread mustard lightly over each biscuit piece. Place a piece of ham and a cheese cube on top.

Fold the edges of the biscuit around the filling and roll into a ball, ensuring the edges are sealed so the cheese doesn’t escape.

Arrange the biscuit balls in a single layer in the air fryer basket, leaving space between them for proper air circulation.

Combine the melted butter, garlic powder, parsley, and salt in a small bowl, mixing well.

Brush the butter mixture over each biscuit ball.

Air fry at 350°F for 5-6 minutes, or until the dough is golden brown and fully cooked.
