Tender Roast Beef - My mother use to make a roast with mashed potatoes almost every Sunday when I was growing up. I think I attempted to make one in my early to mid twenties that turned out to be shoe leather, so I never made another. Although I was hesitant with the recipe, I couldn't have been more pleased with the outcome. The roast was very tender, juicy and delicious. Not to mention extremely easy to prepare.
