Sharon, I do a 5-bean soup in the crock pot which calls for canned beans. I
wouldn't bother with the sugar substitutes in what you have listed above -
not sure why that's even there - but I'd definitely add some dried marjoram
or oregano, say 1/2 tsp, and a couple of cloves of minced garlic. I use
beef stock (or substitute canned defatted broth) or vegetable broth. My
recipe doesn't call for tomato sauce. It does call for ground chili powder.
It's your soup; your call
Make sure the crock pot is set to low; basically all you're doing is heating
this over a long period of time while you're at work or whatever. I use a
little more liquid than you mentioned (but again, no tomato sauce, which
would make up the difference). In the last hour of cooking I throw in 1/4
c. pearl barley. It thickens the soup nicely and adds another little
something.
The canned beans in mine are all drained and rinsed in a collander prior to
putting them in the pot with the other stuff. Off the top of my head (cause
I'm lazy and don't feel like looking) mine has 1 can navy beans (smaller
than Great Northern but still a white bean), 1 can red kidney beans, 1 can
garbanzo beans (chick peas), 1 small can lima beans and a small can of cut
green beans.
