Salisbury Steak and Mashed Potatoes

"Slow Cooker Salisbury Steak and Mashed Potatoes in a SINGLE slow cooker with mashed potatoes, rich gravy, mushrooms and onions over tender beef patties. Slow Cooker Salisbury Steak and Mashed Potatoes. Yep, all in one slow cooker. Salisbury steak is actually a cherished memory for me as it is one of the first meals anyone ever cooked FOR ME. I know that may not be a huge deal, but when you’re a chef people don’t cook for you."
