Hey there TXskimo, don't be skeered of yer krockpot...
Cut up some onions, carrots, mushrooms, celery, whatever... in bite-sized chunks. (fresh rosemary sprigs work very well here)
Take ya some chicken and/or beef bullion cubes/or powder, some water, and whup up a stock.
Put all of the above in yer krockpot. Krank it up.
Git a nice lookin' chuck roast.
salt and pepper the @#$% outta yer meat. Fire up yer stovetop. In yer cast-iron skillet, put in some ahl. When the skillet starts smokin',
throw the meat in.
When the ahl gits smokin' hot, put that meat in. DON'T TOUCH THE MEAT FOR 3 OR 4 MINUTES! Then flip it, DON'T TOUCH IT FOR ANOTHER 3or4 MINUTES!
Yer lookin' fer a good dark brown sear.
Then, you can use tongs to sear the edges.
Crank up the cooker, Put the seared meat in. Put a couple sprigs of crushed rosemary, crushed garlic, onion, and lots of freshly-ground black pepper on top.
Let that phorker go for 2 hours on high, then
throttle it back to medium mode. Check it after 6 hours.
When yer meat is fork-tender, then....
make some mashed taters. Pour Yerself a nice cold bier. You deserve it!
THAT'S what you do with a krockpot.

Don't ask me about barbeque, I know nothing....
