Season and sear the chicken: Season chicken with salt and pepper. Heat oil in a large skillet over medium heat. Sear both sides until golden (about 4–5 min per side). Remove and set aside.
Make the sauce: In a blender, add: cottage cheese, Parmesan, garlic, lemon juice, Italian seasoning, paprika, broth/milk, and cornstarch. Blend until smooth and creamy.
Cook the sauce: Pour sauce into the same skillet over low heat. Stir 2–3 minutes until warm and slightly thick.
Add holiday flavors: Stir in spinach and sun-dried tomatoes.
Add the chicken back: Nestle chicken into sauce, spooning sauce over the top.
Simmer: Cover and cook 8–10 minutes, or until chicken is fully cooked and sauce thickens.
