Prepare the pasta according to the package instructions. Drain and set aside.

Prepare the sauce: In a large mixing bowl, combine the sesame oil, tahini, maple syrup, soy sauce, rice vinegar, garlic cubes, and ginger cube. Whisk until smooth and fully combined.

Add the drained pasta to the bowl with the tahini sauce. Toss until the pasta is fully coated.

Add the scallions, radishes, sesame seeds, and shredded carrot. Mix until the vegetables are evenly distributed throughout the pasta.

Top with additional scallions, radishes, sesame seeds, and, if desired, sliced red pepper and chili garlic paste for extra color and spice.
