Heat dutch oven to medium-high heat and brown the sausage for 5-8 minutes, until just browned. Use a slotted spoon to to transfer the sausage to a paper towel-lined plate and reduce heat to medium.
Melt 1 tablespoon unsalted butter and saute the onions until translucent, about 3-4 minutes; add minced garlic and saute until fragrant, about 1 minute, careful not to burn.
Add the next 6 ingredients (thyme, rosemary, bay leaves, lima beans, corn and broth) and stir to combine. Bring to a boil, cover and reduce heat to a simmer for about 10 minutes.
Stir in sausage, kale and tomatoes, cover and simmer until kale is wilted, about 5 minutes. Remove bay leaves.
Divide stew into six equal servings. Garnish with green onion or chives and cracked black pepper, if desired. Serve with cornbread muffins or crusty French baguette.
