Add the onions and mushrooms to the oil. Add the salt, pepper, Italian seasoning. Stir and cook til tender. The Italian seasoning will be optional if you don't want to repeat the seasong in the gravy since it is in the hamburger. Use 1 Tlbs. I do both but some think it is not needed. I save the left over gravy for biscuits, rice or mashed potatoes so I do include in both the parts of the recipe.
