Heat a large deep skillet or Dutch oven over medium heat. Add olive oil and butter.
Add diced chicken and season with Creole Trinity & Herb, garlic powder, salt, and pepper. Sear until golden brown and cooked through.
Add garlic and zucchini. Cook for 2–3 minutes until slightly softened.
Pour in chicken broth and heavy cream and a little more seasoning. Stir together and bring to a gentle simmer.
Add the frozen Rosina Foods Cheese Tortellini directly into the skillet. Stir, cover, and let simmer for about 5–7 minutes, stirring occasionally, until the tortellini is tender.
Lower heat and stir in pesto, parmesan cheese, spinach, lemon juice, and optional red pepper flakes. Stir until creamy and the spinach is wilted.
Top with extra parmesan and cracked black pepper before serving.
