Pairing question: lamb chops?
One option is an American pale ale. Enough hops to cut through the fat without overpowering, the fruitiness will go well with the gaminess of the lamb, and you probably already have some in your fridge. A Belgian pale would bring more sweetness, and spicyness from the yeast and hops (rather than the bitterness of the APA).
edit: not knowing how much a beer drinker you are, typical examples are Sierra Nevada for the APA and Leffe Blonde for the Belgian
