Ross,
A lot of traditional North African dishes are made out of various ground bean flours...Garbanzo bean, Fava beans and many others...they even do ground lentils (full of iron!).
They make a sort of pan bread using the flour, eggs and salt along with baking soda.
As for the vinager based or pickeled veggies and foods...I did lots of them.
There is an interesting recipe of pickled lemons (use small, young ones). You insize them on 2 sides, rub salt into them and then fill a jar with them, add salt & boiling water. Seal bottles and flip them.
You are supposed to flip them once a week and in 6 weeks the lemons are done...pickled. You then use them when you bake meats and fowl. They use olives with the lemons. makes for succulent dishes.
I make all of my own salad dressing out of either lemon or vinager and cold pressed olive oil. Much healthier & cheaper than the bottled kind and no artificial preservatives either (those are the real killer for me).
Hope that you stay well and happy
Nice to hear that you are doing so well
