Sprinkle 1 oz pkg Onion Soup Mix evenly across steak.
Pour 14.5 oz can stewed tomatoes on top of everything.
Cook on low for 6-8 hours, rotating your insert 180 degrees if your slow cooker does not cook evenly. (I do not recommend cooking this on high. Cooking this on low will give you the most tender results.)

As with any of our recipes, carb counts, calorie counts and nutritional information varies greatly. As a result, your nutritional content depends on which products you choose to use when cooking this dish. The auto-calculation is just an automated estimate and should NOT be used for specific dietary needs.
All slow cookers cook differently, so cooking times are always a basic guideline. Recipes should always be tested first in your own slow cooker and time adjusted as needed.
