Heat oil in a skillet over medium heat. Add roast and brown on all sides; remove to a slow cooker and set aside. Mix soup, catsup, vinegar and brown sugar; pour over roast. Cover and cook on low setting for 8 to 10 hours, until roast is fork-tender. Remove roast to a platter; discard string and let stand for 10 minutes. Shred roast, using 2 forks; return to slow cooker and stir. Spoon meat and sauce onto rolls.
Tip: If soup or stew tastes bland, just drop in a bouillon cube or two to add savory flavor in a jiffy.
"I must say this is the best recipe software I have ever owned."

"I saw lots of recipe software for PC computers but I was having a hard time finding really good mac recipe software. I'm so glad I discovered Cook'n! It's so nice to have all my recipes in a computer recipe organizer. Cook'n has saved me so much time with meal planning and the recipe nutrition calculator is amazing!!!
My favorite is the Cook'n Recipe App.
