How to Make It
In a large saucepan, heat the olive oil. Add the onion, carrot, garlic and chile and cook over low heat, stirring occasionally, until the vegetables are softened but not browned, about 8 minutes. Add the fresh cranberry beans, the spice-herb bundle and the water and bring to a boil over high heat. Reduce the heat and simmer until the beans are tender, about 30 minutes. Discard the spice bundle and season the stew with salt.
Meanwhile, bring a large saucepan of water to a boil. Add salt and the romano beans and cook until tender, about 5 minutes. Drain the beans and keep warm. Just before serving, stir the romano beans into the fresh cranberry bean stew. Season with salt and serve hot.
