Heat a soup pot over medium-high heat, add 1 tablespoon EVOO, a turn of the pan. Add sausage and brown then remove to plate with a slotted spoon to drain.
Add more EVOO to the pot, 2 turns of the pan, and sauté onions and garlic to soften. Season with salt and pepper then wilt greens into the onions. Season with a little nutmeg, add cheese rind, stock and beans, and bring to simmer. Add sausage back to pot and stir in chicken. Simmer until ready to serve, add lemon juice and remove from heat.
