Heat olive oil in pan. Salt and pepper lamb, brown on all sides and place in crock pot.
Add remaining ingredients except orzo. Cook on high for 2 hours. Then low for about 6 more hours.
Remove meat from crock and keep warm. Remove sauce and veggies from crock, place in non-stick frying pan, cook on high for about 15 minutes stirring to keep from burning, until some of the juice has cooked down.
