Cook noodles: Bring a large pot of water to a boil and cook noodles according to package instructions (8-10 minutes) until al dente. Drain and set aside.

Prepare skillet: Heat 2 tablespoons of olive oil over medium heat until shimmering, which takes about 1-2 minutes.

Sauté garlic: Add minced garlic to the hot oil, stirring for about 30 seconds until fragrant but not burnt.

Cook chicken: Add sliced chicken breast to the skillet and cook for 5-7 minutes until golden brown and cooked through.

Add broccoli: Incorporate broccoli florets and sauté for an additional 3-4 minutes until bright green and tender-crisp.

Combine sauce: Pour in soy sauce and chili paste, stirring to coat chicken and broccoli evenly, and simmer for 1-2 minutes.

Finish with noodles: Add cooked noodles to the skillet and toss gently for 1-2 minutes to coat in the sauce.

Season and serve: Adjust seasoning with salt and pepper as needed, and serve hot, optionally garnished with sesame seeds.
