Brown and season pork chops.  While browning chops, cut potatoes, season with prefered seasoning and put in crockpot.  Place chops on top of potatoes.  Open cans of cream of chicken and mushroom into pan that chops were browned in.  Dilute with a little water, enough to loosen goodies stuck to bottom of pan.  Pour over chops and potatoes.  Cut onion into rings and lay across top of chops.  Cook on low for 8 hours or on high for 4 hours or until done.  Serve over rice.
