Baked beans are great when you're 10. You'd eat them 3 times a day if you could.
As you get older you come to realise they're overly sweet and bland.
They are, however, very cheap and convenient and with a little imagination can be turned into a decent adult meal that dehydrates very well.
In a non-stick pan fry a 1/4 tsp of fennel seeds and a 3" piece of chorizo (spanish flavoured sausage - this recipe relates to the cooked / preserved variety) chopped into tiny cubes in a little sunflower oil (if you can't find chorizo a hard italian salami-type sausage will do but you'll need to add 1/2 a tsp of paprika as well).
You can add a 1/4 tsp of red chilli powder while you're frying the sausage - sociable campers may prefer to leave this out
When the chorizo is fried and the parika-flavoured oil has leeched out into the pan add the beans, a teaspoon or two of whole grain mustard, black peppper and a tiny dash of malt vinegar or worecestershire sauce.
You can also add 3-4 pieces of grilled bacon, chopped.
Cook for 5 minutes on a low heat.
Dehydrate as normal, noting the lost weight and rehydrate to eat
