Roasted eggplant and white bean soup with gruyere sausage

Not much left in the ol' cabinets. But I do have some nice sausages, bought on sale. I'm making a roasted eggplant and white bean soup, with some gruyere and roasted garlic chicken sausage added in.

I used this recipe as a starting point, without the fresh herbs or the onion, and all broth instead of broth and water. I'm out of onions, so I'll use half a head of garlic instead (at which point I'll be out of garlic, too). I'm also adding in a red pepper, and of course the package of sausage. I also won't blend it, since my blending equipment is all packed.
