First, brown the ground beef in oil in a Dutch oven-style pan, and sprinkle with salt.
Pour the French onion soup and 1/2 of the can of kidney beans (some liquid from beans is fine – do not drain) into a mini-blender. Blend for 1 minute, pulsing until completely pureed. Then drain the ground beef.
Add soup and bean mixture and all of the remaining ingredients to the pot with beef. Bring it to a simmer, and then turn the heat to the lowest setting and simmer for an hour.
Serve with diced onion, grated cheese, and oyster crackers.
