Use a pastry blender or 2 knives used scissor fashion to cut in the butter until small pea-sized crumbs form.
Add the cheese and toss until coated with flour.
Add the buttermilk and stir until just combined - don't overmix. Drop by 1/4 cup fulls onto the baking sheet about 2 inches apart.
Bake 14 - 16 minutes until golden around the edges. Meanwhile, in a small bowl combine melted butter with parsley and garlic salt.
Remove the biscuits from the oven and brush butter generously over the tops while hot. Best served warm.
