Slice zucchini lengthwise into thin strips.
In a bowl, combine shredded chicken, cooked rice, salt, and pepper.
Lay zucchini strips on a flat surface. Place a spoonful of the chicken-rice mixture in the center of each strip. Roll up tightly and secure with a toothpick.
Preheat your oven to 375°F (190°C). Drizzle the bottom of an oven-safe skillet with olive oil. Arrange the zucchini rolls in the skillet.
Pour the tikka masala sauce over the rolls, ensuring they are evenly coated. Top with shredded mozzarella cheese.
Cover the skillet with foil and bake for 20-25 minutes, or until the zucchini is tender and the cheese is melted and bubbly.
Remove from the oven, let cool slightly, and serve hot. Drizzle with garlic sauce.
