Just bought Bob's Red Mill Whole Grains and Beans Soup Mix...
I haven't tried this one but do have the bob's vegetable soup mix. I cooked that up with my own home made chicken stock, leeks, salt, pepper and garlic. The most important thing to realize about both is that there are no seasonings or salt in them. Bob's does sell a separate spice pack for this and the black bean soup mix which has Chili Pepper, basil, Celery Seed, cumin Seed, oregano, Black Pepper, savory, salt, Garlic, Onion.
So I'd cook it with a good broth and whatever kind of seasonings you think you'd like it to taste like.
