Bring a pot of water to a boil, season generously with salt, and cook the pasta for 3 minutes less than the packet instructions. Drain and set aside.
Add the chicken to a bowl and mix with the dried Italian herbs, salt, and pepper.
In a blender, add the cottage cheese, chicken stock, onion powder, garlic powder, smoked paprika, parmesan, sun-dried tomatoes, and salt and pepper. Blend on high for 2–3 minutes, until smooth and no longer grainy.
Place a large, high-rimmed pan or pot over high heat. Add the sun-dried tomato oil and seasoned chicken, and cook for 3–4 minutes, mixing occasionally. Work in batches if your pan isn't large enough.
Reduce the heat to medium-low. Add the drained pasta to the chicken, then pour over the cottage cheese sauce. Mix well and cook for 1–2 minutes, until fully combined. Add the spinach and cook for a further minute, until wilted. Remove from the heat.
Portion into 5 meal prep containers. Garnish with fresh basil, extra parmigiano reggiano, and cracked black pepper.
