So I thought I would do something a little similar to this.
There were 4 steaks that equaled 2lbs. I added them frozen to the crockpot. I chopped up 2 small onions, sprinkled with garlic powder and a little worcestershire sauce.
I cooked on high for the first hour until the steaks were mostly thawed and I could seperate them. The made a decent amount of their own juice so I didn't add any liquid. I turned the crockpot down to low and cooked for 6 more hours. At this point I was able to start shredded the meat some but not completely.
I added a bag of frozen broccoli and 1/2 cup rice, making sure to get the rice down in the liquid at the bottom. I did however end up adding about a 1/2 - 3/4 cup water.
At this point the kids were home so I kinda lost track of how much longer I cooked it. However I am pretty sure it was around another hour to hour and a half on low. Just until the the rice was soft and I was able to finish shredding the meat.
It turned out so good! The meat tasted very much like a beef pot roast. Next time I will do it with potatoes and carrots and it really will be almost just like a pot roast.
