Soak beans overnight in water.
Drain and place beans in a large pot. Add fresh water, vegetable bouillon cube, squash, onion, garlic, celery, pepper, bay leaves, juniper berries, sage, chili pepper, tarragon, and corn. Stir well, cover, and bring to a heat. Simmer over medium-low for 1 hour, stirring occasionally. May need to replace water lost to evaporation.
Add tomato sauce and tomato paste. Cook for an additional 15-30 minutes, until thick and beans are tender. May add additional water lost to evaporation as needed—should make thick, stew-like consistency. Add fresh mint and stir well. Remove bay leaves. Season with salt, if desired. May serve with fresh tarragon, mint or sage, as desired.
