Melt-in-your-mouth-tender sausage and rave reviews at my large family gathering mean we'll be serving this again. I served it for a noon meal, so I soaked the beans overnight before assembling early-morning, just to make sure they had enough time to soften. I plan to try it with chopped collard greens instead of spinach next time, added about 20 minutes before the end of cook time. The spinach was fine, but I'd like to try a meatier-textured green. I also plan to add a bit of acidity with a tablespoon of vinegar stirred in before service.
