I know there are lots of places where you can buy unprepared lamb but I am looking for already roasted lamb for a wedding. This needs to be from a reputable caterer. Any ideas??? We are looking to feed about 150 guests, so we probably need 2-3 large lambs for this event. Our reception site has agree to serve it if we can find a caterer to provide it. The reception will be in Stow, MA.
