I LOVE my cast iron dutch-ovens.  I've done lasagna, enchiladas, meatloaf, beef & veggie stew, baked spaghetti, chicken & dumplings, biscuits, cinnamon rolls, fruit cobblers, breakfast casseroles, chili & cornbread, mac & cheese.  I just discovered a new pulled-pork recipe to try, and how to make fresh popped popcorn.  Now you have my mind churning on how to make nachos!
