6 persons, should be easy.
how about a quick Muurikka stir? a Muurikka more or less is a shallow steel dish, originally intended to be used as frying-pan over a fire, charcoal grill or similar, even seen it done on a gas BBQ and there are special gas "rings" to buy.
the great part is that you just have to rinse the muurikka out with hot water and then wipe it with a crumpled page from a newspaper (that is if you have not overheated and welded stuff on), before you begin next time heat oil in it wipe with paper and and rince.
the fun part is that all it takes to cook with this is a knife, cutting board and something to stir with, or do as we usually do prepare at home and just pour ingredients in (saves on carying board and kitchen knife), forgot to add a pot to boil the potatoes in.
to eat and save on washing up just use a plate and spork.
quick guide to Muurikka cooking.
cut some sausage and/or meat into pieces same with potatoes, tomatoes, carrots, canned corn and/or babycorn, some peas WITH pods, bean sprouts and such.
first boil the potatoes, I usually boil them almost ready day before and let them finish in Muurikka, or buy ready boiled potatoes and just cut and stir in.
to prepare food just heat Muurikka put some oil in when hot (test with small piece of sausage) throw in meat first let it become almost finished then vegetables in order of cooking time. I usually begin with carrots and potatoes then finish with bean sprouts and pea-pods...
here is one I found on-line with bit more substance to the proportions.
replace the meat with salmon or other fish perhaps some spicy sausages if you wish.
