Newbie with a Dutch Oven

Biscuits! Remember...2/3 of the coals on top, 1/3 on the bottom.

I suggest you do a couple of practice runs at home before camping. Old hand mitts, A lid lifter and chimney starter are helpful.
Learn to balance the amount of heat on top can be tricky.
Start simple making sure you plan plenty of time and have enough charcoal briquettes or coals.
A Fruit Cobbler or garlic pull apart bread to start.

Stew.

I would recommend a chicken stew or pork stew. With meat, carrots, potato, onion. Some oil or bacon fat in the pan to start with and brown the meat a bit. Then throw everything in together. 30 charcoal briquettes - with 20 on top and 10 underneath. Cook for about 45 minutes. Good to go. No leftovers.

Have fun!

Chili please and let us know what time dinner is ready, we will be right over!

Any stew
Chili
Spaghetti
Try biscuits later once you understand heat better.
Most people use too much heat at first.

I too would say a Stew or Chilli with Beans

Chili has no beans.
If you put beans in it then it is something else.
According the International Chili Society.

I recently read and posted that crumpled aluminum foil makes cleanup easier (not easy). Can't verify from experience.

Chuck roast. A few hours and you have a tender meat. Remove and add chicken stock, potatoes, carrots and any other vegetables. Bring to a simmer and cook till done. Really good.
