Brown ground beef in 2 tablespoon hot oil in frying pan. When almost
browned, add onion and continue browning until onion is tender. Pour meat
and onion into 3 1/2 quart crockpot.
Add puree, sauce, paste, water, salt, pepper and oregano and set dial on
low setting. Cut 2 lbs. sausage into pieces and brown in remaining 2
tablespoons oil. When brown, place sausages in sauce in crockpot.
Continue cooking for 12 hours. (If you like your sauce sweeter, you could
add 1/4 to 1/2 cup sugar to this.)
