I don't recall where I got this recipe, but I've been making it for 40 years. The recipe card is covered with food stains as a result of so much use. I like the addition of horseradish, which gives the stroganoff that extra zing.
"This is a super-fast way to prepare Stroganoff without all the extra simmering involved," writes Mary Wilhelm of Sparta, Wisconsin. "For a change of pace, I use boneless chicken breast strips instead of beef. Served with a salad and dessert, your meal is complete."
For a volunteer firefighters' lunch, Corrine Lingberg of Beresford, South Dakota fixed these rich sandwiches that cost a mere 44 cents each. "After just one taste, they couldn't get enough of them," she recalls. "They're great with deviled eggs and baked beans."
