I always buy briskets when they are one sale around holidays and cut them into 3 pieces to use as roasts. I put the roast still frozen in the crock pot with a cup of water and a pkg of onion soup mix. I peas and quarter onions to go all around the roast, what ever will fit. Cover it with a bag of baby carrots, and top with whole peeled potatoes. I take it to work and plug it in, turn it on high. I get to work about 6:30am and by 12:30 or 1, the whole place is screaming for whatever it is that Georgia has brought this time. Sometimes I prepare it the night before and put it in the fridge and it is ready to grab and go.
