Heat olive oil in a large saucepan and saute the chopped onion, the small onions (do not chop them - leave them as a whole) and the lamb.
Let the meat take a brown. Pour salt and pepper, add the bay leaf and the cinnamon. Finish roasting by pouring
the wine and let it evaporate by letting it boil for a while. Add the chopped tomatoes and the tomato paste. Pour some
water and let it cook for 1 hour in 150 C until the sauce thickens. Serve with fried potatoes.
