Quick and Easy Hamburger Hash

Ingredients :
1 lb   ground beef
1 small   onion, chopped
1 tsp   chili powder
1/2 tsp  cumin
4 medium  potatoes, peeled and cubed (can leave unpeeled if desired)  
   cooking oil 
                  salt and pepper  
                  red pepper flakes, optional
1  (10-oz) can cream of mushroom soup
1 1/2 c  sharp cheddar cheese, shredded
1 -Preheat oven to 350 degrees
2 -In heavy (oven safe) skillet over meduim heat; brown beef and onions. Season with chili powder, cumin, salt and pepper. Drain off excess oil or blot out with paper towels.

NOTE: I used a cast iron skillet.
3 -Meanwhile in another skillet over medium/high heat, coat bottom of skillet with oil. Heat oil; add potatoes to hot oil. Season with salt & pepper and red pepper flakes. Fry potatoes until they start browning. They need to be almost done. They will continue cooking in oven. NOTE: If there is excess oil, slide potatoes to the side and blot excess oil up with paper towels.
4 -Add cream of mushroom soup to beef; stir to mix. Add potatoes and 1 cup of cheese, toss to mix. Top with remaining cheese.
5 -Bake in preheated oven for 20 minutes. Should be bubbly around the edges of skillet before you remove from oven.

This time is based on all ingredients being hot before going into the oven.
