Place cube steak in the bottom of your slow cooker.
In a bowl, mix together onion soup mix, cream of mushroom soup, cream of chicken soup, and water.
Pour the mixture over the steak.
Cover and cook on low for 8 hours. Resist the urge to peek!
Once cooked, give it a gentle stir and season with salt and pepper as needed.
Serve with mashed potatoes, rice, or cut into chunks for the perfect finger food.
