Southern Fried Cabbage with Sausage

This is a really simple quick dinner and it always hits the spot.  Sorry that that picture is of a mostly empty skillet--almost forget to take a photo!

3 T olive oil
1 small green cabbage, sliced
1/2 onion chopped
1 lb chorizo chicken sausage, sliced
1 can diced tomatoes, undrained
salt, pepper, garlic powder, and Tony Chachere's Seasoning to taste

In a large skillet, brown the sausage. Remove, and melt butter in skillet and add cabbage and onions and cook for 5 minutes or so. Add remaining ingredients and then add the sausage back in. Cover the skillet and cook for about ten minutes. Uncover, and finish cooking until cabbage is desired tenderness and most of the liquid has been reduced.
