Chop the veggies into big chunks and toss into a large dutch oven or roasting pan. Then dump dried beans and water in as week. Mske sure all the beans are submerged have about 2 extra inches of water. Add the rosemary (you can opt out or use other spices you like) and season well (like a few teaspoons) with salt and pepper oven. Place the dutch oven into oven with lid on and let bake for about an hour and a half to 2 hours, checking and giving it a stir ever now and then and making sure the water has not evaporated before beans are done If so, add in another cup or 2.
Once beans are cooked to your liking, remove from oven, taste and season with more salt and pepper if needed and , well, eat it.
Left overs are fantastic for future salads, grain bowls, wraps, added to stalk for soup,or just reheated and eaten.
