Skillet Sweet Potato Sausage and Spinach Hash

Mom discovered this recipe and it is tasty!!  The name needs some work though.  It's too long!!  Anyway here it is!

2 small or medium sweet potatoes, peeled and diced small (we use yams)
1 apple, peeled cored and diced small
2 T oil divided
1/2 lb. browned Italian sausage (break up in small pieces while browning)
1 10 oz bag fresh spinach
1/2 onion chopped small
1/4 tsp cinnamon
salt and pepper to taste

In large nonstick skillet heat 1 T oil over medium high heat.  Once heated, add sweet potatoes, apples, onions, and cinnamon.  Cook until softened.  About 10 minutes. Mix sausage into sweet potato mixture and add the spinach.  Cover for a few minutes until spinach is wilted and then mix well.
