I found most beans were ok, but some lentils gave me a massive spike.
Same with veg, some are ok, root veg again gave me a bad reading.
So my stews are a selection of beans, (butter beans go well with chicken, kidney beans if I put chili in, chick peas if it's curry, mung beans, pinto beans, are also ok with me.
Either tinned or pre soaked and boiled.
Any veg I have from the selection I know is ok, usually green beans, onion, mushroom, peppers, peas, cauli, broccoli, courgette.
Garlic, chili peppers, or indian spices, chinese, or French herbs depending on what I want.
Any meat I want to add, or leave it as just the beans.
All in the crock pot, and I prepare a batch for the week to freeze.
I tend to make a general base now, out of ingredients I know work for me, freeze it in meal sized portions, then add the various spices/herbs when I microwave it, which works surprisingly well to give a curry one night, chicken chasseur the next, chili the next, Chinese the next.
