IMHO, the best bet for cooking at home is a 2-burner Coleman or similar propane stove. You can find them for $10 at yard sales or around $30-40 new. I used one for almost a week when we lost power due to the Halloween snow storm. Cast iron frying pans work best, but regular cookware will also work. You will need a percolator to make fresh coffee, or settle for instant. Don't forget to keep a good supply of propane canisters, they fly off the shelves when the power goes out.

I noticed no issues with CO using the Coleman stove inside. I have CO detectors on each floor and neither made a peep.
