Meatloaf

I'm not certain how this is going to turn out - 2 lbs. ground lamb, 1 c. oatmeal (not the quick-cooking kind), 1 smallish onion (diced), garlic, mustard, rosemary, cumin and nutmeg. Mix well, form into loaf, bake at 350. I'll let you know for how long when it's done - I'm cooking to 160 on my meat thermometer, and expecting it take somewhere between 45 minutes and 2 hours.
