Updated Shepherd's Pie – Better-for-you and ready for the dinner table in less than an hour? Say it isn’t so. We took a classic recipe and gave it a Healthy Living makeover by replacing the butter in the mashed potatoes with KNUDSEN Light Sour Cream and KRAFT 2% Milk Shredded Cheddar Cheese. Plus, we used extra-lean ground beef instead of regular ground beef. All that, and still just as tasty!
