We've talked about doing this since before we were married, but somehow never actually did it until this year...
No electric lights, no forks, no spoons. Just a 'dagger' (steak knife) per person, some meat and veggies boiled in a pot, and a big blob of bread.
Corned beef, potatoes, carrots, all baked in a cast iron dutch oven (which I confess I put in the oven because I didn't feel like building a fire)
Honey Oatmeal bread, also baked in cast iron. We ripped off hunks rather than cutting it, and used it to sop up the juice from our meat. Mmmm, so yummy!
