Lightly grease a ½ sheet pan and preheat the convection oven to 325 degrees. Slice each Bridgford Biscuit in half horizontally, then place the top and bottom halves back together and arrange them on the prepared sheet pan. Bake for 7 to 10 minutes, or until the biscuits are golden brown. Remove from the oven and lightly brush with melted butter or margarine. Separate the biscuit halves, place one cooked and heated chicken nugget on each bottom half, then replace the top halves. Serve warm.
