Heat butter or bacon fat in large skillet over medium heat. Add diced onion and pepper and cook for about 3 minutes or until it starts to get translucent.
Add the potatoes and cook for about 15 minutes, stirring occasionally. Toss in turkey, minced garlic, chopped herbs, salt and black pepper and cook for about 5 minutes or until you start to get a char on the potatoes.
Check for seasoning. Top with warm turkey gravy and serve.
