Heat olive oil in a large non-stick saucepan over medium-high heat. Crumble sausage into 1-inch pieces and add to saucepan. Cook sausage, stirring occasionally until cooked through. Drain sausage onto a plate or baking dish lined with paper towels leaving 1 tsp fat in pan, set sausage aside. Add diced bacon (being sure to separate pieces from each other if you stacked them when slicing) to fat in saucepan, return to heat and saute 5 minutes, stirring occasionally. Add diced onions to bacon in saucepan and saute mixture until bacon is cooked through (not crisp) and onions are tender, about 5 minutes longer. Add chicken broth, water, sliced potatoes, sugar, fennel seeds, salt and pepper. Bring soup just to a boil then reduce heat to medium-low and stir in half and half, kale and cooked sausage. Cover saucepan and simmer 25 - 30 minutes, stirring occasionally, until potatoes are very tender. Use a spoon or ladle to remove excess fat from top of soup if desired. Serve warm topped with Romano cheese.
