I'm in process of trying a recipe with bean flour. I raise a variety of dry beans and I just mix em' all together for the flour. I still have to cook the noodles to see if they're worth making again.
Here is a recipe we like. We use regular white, pastry or Eincorn flour.
We are experimenting with a few flour mixtures at the moment so there might be more on that later.
Ezekial flour is one that we like with this recipe, although this recipe calls for salt I don't add any salt in the dough...
