If you haven't already, check out the
value added meals in canning jars (though I think they are fresh cooked foods, not canned)
thread farther down in this forum.
I think healthy heat-up meals is a huge need almost any where. Maybe find a way to connect it to something nearby.
For example, my town is a winery town, and on Saturdays, there is a HUGE amount of people wine tasting up and down the valley. What do you need when drinking wine (and or to be able to drink more without getting too drunk)? Good food. Most of the wineries are not restaurants. They might have cheese and crackers or something light, but not much that would be considered a meal or substantial
enough to help with all that alcohol.
Plus, I have this gourmet food aficionado friend of mine who is a slow food enthusiast. He just returned from Spain and is in withdrawal from a cured ham called jamon. There are pig growers nearby whom he buys from, but some grind all of what could be ham into sausage instead of curing it for a much higher price per pound. He ends up curing a lot of his own meat (in his wine cellar, because it's temperature and humidity controlled) primarily because he can't find a
local product of high enough quality. He also said that buying a local, fresh leg of pork is often more expensive than buying imported cured hams.
There's got to be a way that
permaculture methods could cut those costs. In any case, I do think cured or smoked meats are a fantastic idea.
Fermented foods are an awesome idea, too. In fact, if I knew of a local source for organic (doesn't have to be certified) fermented cabbage/sauerkraut, I would buy it. If anyone in my area has a tip, let me know!
