Preheat grill or grill pan to medium-high heat.
Rub chicken with olive oil, garlic powder, Italian seasoning, salt, and pepper.
Grill 5–7 minutes per side until internal temp reaches 165°F (75°C).
Let rest 5 minutes, then slice thinly.
Step 2: Cook the Pasta
Boil fettuccine until al dente per package instructions.
Reserve 1/2 cup pasta water, drain pasta, and set aside.

Add garlic, sauté 30 seconds until fragrant.
Stir in cream, then Parmesan, salt, pepper, and nutmeg (if using).
Stir until creamy and smooth. Adjust thickness with reserved pasta water.
Step 4: Combine and Serve
Toss pasta into Alfredo sauce until coated.
Top with sliced grilled chicken and garnish with parsley.
