A Little Irish Tradition

OK, well I'm not Irish, but growing up we ate a lot of Shepherd's Pie - mainly because in a big family, a little has to go a long way. This differed from my family's traditional take though, calling for lamb shoulder instead of ground beef and peas (which I think really pulled it all together). Aside from the slow cooking of the meat, the recipe is not very much work and the leftovers will last you for days!
