Slice the steak into thin pieces, sauté with olive oil. When browned, add white onion, peppers and mushrooms until slightly soft. Transfer from stove to Crock-pot.
Next, make the brown gravy mix packet--in the frying pan you just took the meat and vegetables from. Thicken slightly and add to the mixture of meat and vegetables in the Crock-Pot.
Cook on low for 4-5 hours. Serve on whole wheat buns with a pickle spear.
Cooks Note: If you don't have brown gravy mix, substitute 1 Knorr beef bouillon cube, 1 tablespoon Wondra flour, 1 tablespoon butter, 1/4 teaspoon Gravy Master, dash of black pepper, 1/2 teaspoon onion soup mix and 1 1/2 cups water. Combine in frying pan as above, bring to boil for 1 minute and add to Crock-Pot.
