Pork Stew over Rice

I think this might have overcooked a bit.  It was still good. 

1 pound pork stew meat
1 onion sliced
5-6 large carrots, peeled and thickly sliced
2 cups chicken broth
1 packet gravy mix

Spray the well of a crockpot with cooking spray.  Add the pork, onions, and carrots.  Mix the gravy packet with broth until dissolved.  Add a little salt and pepper to taste.  Pour over the meat mixture.  Set crockpot on low for 6-8 hours.  Serve over rice.
