Heat olive oil in a large skillet over medium heat. Add sliced chicken sausage and cook until browned. Remove and set aside.
In the same skillet, sauté onion until softened; add garlic and cook until fragrant. Stir in orzo and toast for 1 minute.
Pour in chicken broth and seasonings; bring to a simmer. Cook until orzo absorbs most of the liquid (8–10 minutes).
Lower heat and stir in cream and cheese until smooth. Return sausage to skillet; mix in greens and sun-dried tomatoes.
Garnish with parsley and lemon zest before serving.
