Prepare Ingredients: Chop the boneless chicken breasts into bite-sized pieces, mince the garlic, and cut the broccoli into florets.

Cook Pasta: Boil salted water in a large pot. Add pasta and cook until al dente, about 8-10 minutes. Reserve 1 cup of pasta water before draining.

Sauté Chicken: Heat olive oil in a skillet over medium heat. Add chicken pieces, seasoning with salt and pepper. Cook until golden brown and cooked through, about 7-10 minutes.

Add Vegetables: Stir in minced garlic and broccoli florets. Sauté for about 5 minutes until broccoli is tender-crisp.

Incorporate Sauce: Pour in soy sauce and half a cup of reserved pasta water. Stir gently to combine flavors.

Combine Everything: Add cooked pasta to the skillet, tossing gently to coat with sauce.
