I'm getting pretty good about freezing leftovers to make other meals with later. I used to never do that, but I'm kind of enjoying it now.
I had a package of leftover cut up roast that I defrosted and used in this stroganoff. So all I had to do was boil the noodles, and whip together the stroganoff part by sauting onion and fresh mushrooms in margarine, then adding a little cornstarch disolved in water, then add in a cup of water w/ a beef bouillon cube disolved, a little sour cream, cream cheese, the roast and seasonings. And there's enough left over for a lunch for the two of us later this week.
