Mom's Stroganoff

What's more appropriate for Mother's Day than a recipe that was passed down from my grandma to my mom to me?  My grandma could whip this together from memory so my mom made her write it down.  My mom made her own changes and this is the version she gave me last time I asked for it.  I've made it a couple times now, so maybe it's my turn to put a twist or two on it!  Although it's already a five star dish just the way it is.  Thanks Mom!
