Award-Winning Italian Beef

1 large roast (your favorite cut- but trim the fat if yours is a fatty cut)
1 package Good Season's Italian Dressing mix
1/4 cup vinegar
1 T. sugar
1-2 cans chicken broth
1 tsp. garlic powder
1 package brown gravy mix (mixed with one cup water)
1 green pepper, sliced
1 small jar pepperoncini AND juice

Pierce meat with a fork. Mix all other ingredients and pour over meat. Cover and let marinade overnight OR at least 8 hours.
*THIS IS THE SECRET TO THE BEST TASTING ITALIAN BEEF EVER! DON'T SKIP THIS STEP!

Cook on low for about 8-10 hours depending on the size of your roast. *Really, the longer it cooks, the better it is. Let it cook till the meat falls off the bone! When done, SHRED THE BEEF. Serve in large hard, crusty rolls or hoagie buns. Put small bowls out for each guest with dipping juice in them. The sandwich can be dipped in bowl before each bite (this is why the hardest, crustiest bread is best!) Also serve with a bit of shredded mozzarella.
