I used to cook with lamb breast all the time when I lived in the uk -it was cheap and we were poor.
I used to cut it between the ribs (and slice the remaining flesh into strips), boil it for a short while, coat it in some kind of sauce (from memory I want to say sweet and sour) and then bake it in the oven for a time...
Kind of like pork ribs really, but lamby.
I would cook them just like you would cook ribs... but don't expect it to taste like pork
