Bring a large pot of water to a boil. Add ½ teaspoon salt, then add 1 ½ cups (180 g) dried pasta and cook according to the package directions until al dente.
While the pasta cooks, place 8 ounces (225 g) cherry tomatoes and 3 cloves minced garlic in a deep baking dish. Drizzle with 1 tablespoon (15 ml) extra virgin olive oil and sprinkle with ¼ teaspoon ground black pepper. Toss to coat the tomatoes and roast in the preheated oven for 7–8 minutes, until the tomatoes begin to soften and pop. (Leave the oven on.)
Drain the pasta well and add it to the baking dish with the roasted tomatoes. Add 3 ounces (85 g) baby spinach leaves and 3 tablespoons basil pesto. Toss everything together until the pasta is evenly coated and the spinach begins to wilt.
Return the baking dish to the oven and bake for 3 minutes to heat through and wilt the spinach fully.
Remove the dish from the oven and arrange 5 ounces (140 g) fresh mozzarella (sliced or torn) evenly over the top. Return to the oven and bake an additional 3 minutes, or until the mozzarella is just melted.
Remove from the oven. Sprinkle red chili flakes as desired, scatter fresh basil leaves for serving, and serve immediately.
