Add the diced chicken, season with salt and pepper, and cook until browned and cooked through, stirring often.
Stir in the cherry tomatoes and cook for an additional 3-4 minutes until they start to soften and burst.
Add the cooked linguine to the skillet and toss to combine.
Remove from heat and stir in chopped parsley.
Serve with grated Parmesan cheese on top and more cracked pepper if desired.
Notes
Reserve a little pasta water to loosen the sauce if needed. This dish is forgiving, so you can adjust the seasonings and ingredients according to your taste.
