Combine cream cheese, bacon, onion and pepper in a bowl.
Separate crescent rolls into two rectangles. Pinch seams together. Spread half of cheese mixture on each of the rectangles. Roll up, starting at longest side, and seal. Cut each roll into 16 slices. Place slices, cut side down, on a baking sheet.
Bake for 15 minutes or until golden-brown. Serve warm.
