There's really not much that you can cook at home that you can't make while camping. Depends mostly on how much time you want to spend cooking, and how much gear you're willing to haul.
For a beginner, especially, I would keep things simple. Steaks, burgers, etc.---the sort of stuff you'd make on the backyard grill---along with foil meals probably make the most sense.

In general Phil is correct. Most campfire cooking is done over coals, not over direct flames. There are exceptions, though. For instance, anything requireing boiling can be done over direct flames.
Cast iron makes the best cookware for campfire cooking, btw. But if you don't have any, don't sweat it. Just as at home, any pot and pan can be made to work.
