If you are not used to camping, you don't want too many surprises. If you have some easy good one pot meals that you make at home, why not use that?
How much work do you want to do? Heating a can of beef stew might be simplest for someone that does not camp very much and wants an easy meal.
If you get a pre-packed rice meal, look at the instructions first because some need to simmer for a long time while others only need a short simmer. When I am camping and hungry I want the shortest simmer possible. But, I usually take the time to dice up some onions and peppers.
