This recipe is great because it doesn't require many ingredients, and is definitely a cost-effective way to make stroganoff.

It might be helpful to clarify a couple of points within the recipe and make a few adjustments. At the second step "sprinkle mixed flour, salt, and pepper over meat", you can also cook the meat in a separate pan, drain out the grease once the meat is cooked to reduce fat. Then instead of adding the meat and mushrooms together at the same time add the mushrooms to the butter/onion/garlic saute pan, cook for a few minutes, THEN add the meat and cool.
