Crockpot Beef Carnitas

This is a Pinterest find (other than subbing beef for pork), from this site (not sure if it's her original recipe).  It was one of those meals that the whole family loved.  The girls both asked for seconds.  

1 nice sized (3ish lbs) beef roast (not sure what kind I picked up), trimmed and cut into chunks. 

1/2 cup freshly squeezed orange juice

juice of 2 large limes

good amount of salt and pepper

2 tsp ground cumin

4 cloves garlic, minced

I try to do as much prep for the week on Sunday as I can, so I mixed up everything and put it in a ziploc bag for a few days before I dumped it into the crockpot for 7 hours on low.  So easy and so good!
