It depends were you are camping. If I'm in the back of beyond (NW Scotland, Norway etc) then it's variations on pasta'n'tuna, pasta'n'ham, pasta'n'sausage with whatever veggies are to hand. When I got back from 4 weeks in Iceland I couldn't face tinned tuna for a year!
If you are somewhere were there are plenty of shops just buy what you would normally eat before you get to the campsite, assuming you've got a sensible cooking kit.
Example:
Stodge - Couscous, just add boiling water & oil/butter/spices. Quick cook rice in a bag is good as well.
Veg - in a saucepan, gently fry onions/garlic/diced peppers or fine beans, add a couple of chopped tomatoes and simmer.
Meat - Lamb steaks or chops, cooked to taste.
You'll need to juggle the pans over the single burner so everything is ready at the same time.
Wine - a decent Rioja or Cabernet Sauvignon
Enjoy!
My cooking kit:
Trangia 27 with an extra small pot from a mini Trangia. Gives 3 saucepans of different sizes & a decent frying pan.
Chopping board / strainer - a circular disc that goes on the bottom of the Trangia.
Spatula or wooden spoon - Sharp knife, Opinels are very good for food prep.
Plate, knife,fork,spoon. Sometimes a proper corkscrew.
Herbs & spices, tube of tomato puree, tin of Marigold stock.
