In a large bowl, combine and mix the cubed chicken with 1 Tsbp olive oil, and 1 tablespoon of the blackened seasoning.
Heat a large skillet on medium-high heat with 1 tablespoon olive oil. Once it's hot, cook the chicken for 5 minutes, flipping about half way.
Add the green onions, and the green and red bell peppers. Cook for 2 minutes, or until the chicken is fully cooked through.
Remove the the mixture from the pan into a bowl. Cover and set aside.
Reduce heat to medium, and add 1 tablespoon butter.
Add the garlic and ½ tablespoon blackened seasoning, cook for 1 minute.
Pour in the chicken broth, and scrape up any browned bits off of the bottom of the pan.
Add the linguine pasta. Bring to a simmer, and cook for 10 minutes. Stir and scrape the pasta every few minutes to keep it from sticking to the pan.
Add in the cream cheese and stir until melted. Add in the parmesan cheese and stir until melted.
Turn off heat.
Stir in the lemon juice, and the chicken mixture.
Ready to serve! Serve with optional garnish & toppings.
