Cook the pasta according to the package instructions. Drain the water and set it aside.
Heat a large skillet over medium heat and add olive oil. Once the oil is heated, add the minced garlic and cook for a minute until the fragrance emerges.
Stir in the sun-dried tomatoes and capers, and cook for 2 minutes.
Add the canned tuna and break the chunks using a wooden ladle. Season with crushed red pepper flakes, salt, and pepper.
Add the cooked pasta, Kalamata olives, and pesto sauce. Gently toss the pasta. If needed add about ⅓ cup of pasta water for consistency.
Once done, garnish the tuna pesto pasta with toasted pine nuts and shaved Parmesan cheese on top. Serve it while it's still warm.
