SIMMER – Add the garlic, bay leaf, paprika, salt, pepper and chilli flakes and cook. Stirring occasionally, until fragrant, about 5 minutes. Stir in the beans, stock base, and tomato paste, then add 6 cups water. Increase the heat to high and bring the soup to a simmer, then reduce the heat to medium-low. Gently simmer the soup partially covered and stirring occasionally, until the veggies are tender, the beans are buttery when mashed against the side of the pot, and the flavours have melted, about 30 minutes. Taste and adjust the seasoning with more salt and/or pepper, if desired. Remove and discard the bay leaf.
