- Cook the whole grain fusilli in salted boiling water according to package instructions until al dente, then drain and toss with a drizzle of olive oil to prevent sticking.
- Slice the chicken breast into thin strips and season with salt and black pepper.
- Heat olive oil in a pan over medium-high heat and sauté the chicken strips for 5–6 minutes until golden and cooked through, then set aside.
- In the same pan, add the sliced leek and minced garlic, cooking over medium heat for 4–5 minutes until softened and fragrant.
- Stir in the heavy cream and cream cheese, mixing until a smooth, thick sauce forms. Return the chicken to the pan and simmer for 2–3 minutes. Season with lemon juice, salt, and pepper.
- Slice the red bell pepper into thin julienne strips and arrange them fresh over the plated dish.
- Arrange lettuce leaves as a base on a wide plate, spoon the fusilli on one side and the creamy chicken and leek mixture on the other.
- Garnish both sections generously with black sesame seeds and serve immediately.
Tip: For a silkier cream sauce, add a ladle of the pasta cooking water to the leek and cream mixture — the starch helps emulsify the sauce and prevents it from becoming too thick.
