Separate the biscuits. Place one biscuit in the center and place the remaining 9 in a circle around it, edges slightly overlapping. Gently press them together. You should get about a ten inch circle(with pretty scalloped edges).
Combine olive oil (you could use melted butter) and chili powder. Brush over the biscuits. Sprinkle with chilies and cheese.
Bake for 12-15 minute until nice and golden brown.
To serve; pull them apart.
I have also used olive oil, chopped garlic, fresh minced rosemary and parmesan cheese.
