Over the years Mrs. BD has found the recipe for the best-ever meatloaf. Sorry - I don't have the recipe right now, but I know it includes ground pork, lamb, and beef, plus of course mashed on the side. It's the lamb, I feel, that makes it so tasty and crunchy on the edges. Excellent for a sammich later, too.
I was reminded of Lamb Burgers by the menu of a popular midtown Manhattan Irish pub, Connolly's, on 47th St. Irish (not entirely) pub menu. Since our neighborhood Scots/Irish pub closed this year due to crazy rent, we need something like that once in a while. Yeah, a good Shepherd's Pie can be nice but I've had some disappointing ones. Mrs. makes an excellent one.
Everybody on this planet seems to like a burger, but a lamb burger is less routine and has more flavor: Lamb Burger. I like tomato slices and red onion slices on the side with any burger. Fries (aka chips) of course.
Off-topic, in Scotland they will serve mutton as "lamb". Trust me - it's mutton but you could call it "older lamb." There's an English insult, "Mutton dressed as lamb." Know what it means?
In the mood for a mutton chop? In NYC, it's Keen's (since 1885).
