Mimmie's Beef Stroganoff

This recipe came from my husband's grandmother, whom we call Mimmie. I wanted a recipe that didn't require cooking with wine, and that I had all the ingredients on hand. She pulled through for me, so I am accrediting her with this. I do leave the onion out of my recipe, because of allergies, but I included it in the ingredients and directions for those who like it. Cooking time is an estimate.
