We have this on rainy days as it is nice and warming and it doesn't matter if the gas is warming the caravan during the cooking.
Enough rice for the people you are cooking for. ( I used two bags of rice for four people)
Some oil
A packet of green thai curry paste.
1 tin of coconut cream.
I packet of chicken drums or whatever you managed to pick up last time you went into town.
Method - Put a non stick frypan or large pot onto your cooker. Place the chicken in and brown. As the chicken is browning cut up an onion and put it in too. Once browned add 2 tablespoons oil and the green curry paste. Let the paste cook for a minute. Add 1 cup of water and bring to the boil. Add the amount of rice you need. Stir well and start adding veges as you chop them up. Once all the veges are in (do lots) then add the tin of coconut cream (or milk) and another cup of water. Let it simmer while you watch a DVD with the kids. Keep cooking until the rice is done and make sure that the chicken is cooked through to the bone. Add more water if needed. Serve in a bowl with rice and vege on the bottom and a drumstick per person on the top.
Vege selection - use anything that is looking like it will not last too much longer as well as what you have fresh
Rice - I keep the boil in the bag only in the caravan as it is tidy in a box and it makes no mess when cooking (which is a big deal when camping - the easier the better)
Oil - I have rice bran oil as it is square and so easy to store in the caravan or your food box and it has a high burn point so will do for everything you need when camping.
Thai green curry paste - I love the Asian Home Gourmet brand as they are very authentic. Also camping they are the right portion size so there is no waste or no bottles etc that you have open that could go off in the summer heat. This is quite spicy for kids. You could use red curry paste which is much milder if you wanted.
