Preheat the oven to 350 degrees F. Spray a 16-cup muffin pan with nonstick cooking spray.
Using kitchen scissors, cut the biscuits into fourths. Pour the melted butter into a small bowl. Dip each biscuit piece in the butter, and place 3 pieces in each muffin cup.
In another small bowl, combine the salt, pepper, onion flakes, poppy seeds and sesame seeds. Sprinkle the seasonings over the tops of the biscuits. Bake until golden brown, about 20 minutes. Serve immediately.
