Cook the linguini according to the package directions and drain.
While it is cooking, combine butter, lemon juice, basil, garlic powder, and lemon pepper in a saucepan; simmer until butter is melted.
Add cooked chicken; stir until chicken has been reheated.
Add drained, cooked pasta and toss to coat. Sprinkle with Parmesan cheese. Serve immediately.
This recipe uses cooked chicken from the freezer. If you are not cooking chicken in bulk and freezing it, you will need to allow time to sauté the chicken (this can be done while you are cooking the linguini).
