My mom fixed a lot of moose dinners while I was growing up in Alaska. My mother-in-law, who currently lives in Alaska, is visiting us now. I asked her about the situation you are in, and she claims you can could cook either the same way you would cook beef. Keep in mind moose is "gamey" tasting. As I recall, it depended when in the season your killed a moose as to whether it was fit to eat or not. If they were in the "rut" we wouldn't even bother to kill the things. Maybe you could google the topic and get better results.
