Preheat oven to 400 degrees. Prepare a baking sheet with cooking spray
In large bowl, mix together biscuit mix, garlic powder and cheese.
Add in milk and mix until well blended. Note that this will get very sticky.
With a spoon or your fingers shape the dough into clumps and place them on the baking sheet. If you would like them to be uniform you can pat down the peaks--the dough will hold its shape when baked.
Bake for 10-13 minutes or until biscuits begin to brown slightly around the edges.
While the biscuits bake, prepare the warm butter mixture by mixing together the melted butter, oregano and garlic salt in a small bowl.
When biscuits are done brush the biscuits with the melted butter mixture until they are well coated.
