Featuring convenient canned biscuits stuffed with ham and cheese, these flaky, buttery bites will delight party guests and tailgaters alike.
Preheat oven to 350°. Spray a 24-cup mini muffin pan with cooking spray. Divide dough into 8 large biscuits. Using a sharp knife, cut each biscuit into 3 triangular sections for a total of 24.
Arrange one piece of dough with a long side facing you. Make 3 short deep cuts (like hash marks) across the top, positioning each cut about 1/4" apart from the next and cutting deeply but not all the way through.
Using a butter knife or offset spatula, spread some mustard inside cuts. Fold 1 piece of ham in half and stuff in center cut. Fold 1 piece of cheese in half and stuff in center cut beside ham. Repeat with 2 two side cuts. Place biscuit in a prepared muffin cup, ham and cheese side up. Repeat with remaining biscuits and fillings. Brush tops of biscuits with some butter; reserve remaining butter.
Bake biscuits until golden brown, 14 to 18 minutes. While still warm, brush with reserved butter and sprinkle with salt (if using). Serve warm with more mustard alongside, if desired.
