Sauce for Lamb?

My Dad has been eating a lot of lamb lately and is looking for savory sauce (not sweet..since he has diabetes) Most mint jellies are loaded with sugar, plus he doesn't like sweet sauces on meats in any case. I can't really help him since I don't care for lamb myself, but was wondering if someone could recommend something.

He says that he uses salt, pepper, garlic and olive oil as prep. Sears it on both sides in a grill pan and finishes it in the oven.

Any suggestions?

Thanks,

Richard

Not something I eat either, but Della, our chef at my workplace, browns lamb chops in a frying pan, puts them in the oven to finish, and deglazes the frying pan with red wine and a little broth, then stirs in some butter and whole grain mustard to make a sauce.

For lamb roasts she uses a rub of rosemary, garlic, dry mustard, and ginger. No sauce with that though.

A tart and chunky cranberry sauce. If that is still too sweet, then, um, er, maybe a mushroom ketchup?

Tzatziki. Gotta use real Greek yogurt though.
