Roll pieces of chicken in cajun seasoning until coated.
Heat olive oil in a large deep skillet over medium heat. Cook chicken until browned, about 7-8 minutes.
Meanwhile, cook linguine in salted water, al dente. Set aside.
Add garlic and bell pepper to skillet with chicken and cook until pepper is tender, about 3 more minutes.
Turn heat down to medium-low. Add butter, coconut milk, sun dried tomatoes, paprika, parsley, lemon juice, and a couple grinds of fresh black pepper. Mix to combine ingredients.
Stir in parmesan cheese. Heat through until cheese is melted and sauce begins to thicken, about 3-5 minutes.
Add the cooked pasta to the skillet and stir well until noodles are coated with sauce.
Add green onion and additional black pepper, if preferred. Enjoy!
