Boil the beans for 2 hours (half this time if previously soaked). Change the water at least 2 times. Don't skip this step! Beans are hard to digest and if you didn't soak them overnight they will release bad enzymes into the boiling water, which will cause bloating.
Heat the oil in a large pot.
Sauté the onion for 2-3 minutes.
Add the drained beans.
Add water just enough to cover the beans.
Add bay leaves, pepper, salt, fresh tarragon, chopped garlic and paprika.
