NCHFP has directions for canning them both as dried (as in dried on the vine) or fresh shelled. If dried on the vine, the most common way, you just use the Dried Beans or Peas instructions. If picked and shelled fresh you use the Fresh as in Lima Beans instructions.

Otherwise yes, they can be lightly roasted till golden brown and hard, lightly salted and vacuum packed for storage. And they can be blanched and packaged for freezing.
