Not vegan, but vegetarian. From a blog called "Low Fat Vegan Kitchen" by Susan V. Jackson.
Vegetable broth may be subbed for the 5 cups of water for a richer flavor.
Prep time does not include overnight soaking for the peas.
Heat the oil in a heavy pot. Add onion, pepper, and celery, sweat over low heat until softened.
Stir in garlic, continue stirring until garlic releases it's aroma.
Add all remaining ingredients except liquid smoke to the pot, along with enough additional water to cover the peas by one inch. Cook until peas are completely tender, about 1 1/2 to 2 hours, adding more water as necessary. When they're tender, add the Liquid Smoke, cook for 5 more minutes, and serve over rice.
