Crock Pot Cranberry Pot Roast

I saw this recipe on another food blog (but can't remember which one now, sorry) and as I had a bag of cranberries I needed to use, I decided to give it a try.
It turned out pretty good, you can definitely taste those cranberries!

2 lbs beef roast
1 bag of cranberries
1 apple
1 onion
1 potato
Juice of 1 lemon

Coat beef in salt and white pepper
Place cranberries in bottom of crock pot, pour the pineapple and orange juice on top of cranberries
Add chopped onion, potato and apple
Cut the roast into smaller pieces and add to the crock pot, pour lemon juice over the meat

Add rice and cook an additional hour
