Here's a really good beef recipe and simple to make.
3lb rump roast
1 jar mild giardiniera (drain the juice)
2 cloves garlic
1/8 cup chopped oregano
Mix the ingredients into a slow cooker with the roast and let it cook for approximately 10-12 hrs, the meat produces it's own juices and will literally fall apart.
Best served on gonella bread with a side of pepperoncini
