Begin by cooking the soba noodles according to the package instructions until they are al dente. Once cooked, drain the noodles and rinse them under cold water to quickly halt the cooking process. Set them aside in a large bowl.
In a separate bowl, combine the sesame oil, soy sauce, rice vinegar, and chili garlic sauce. Whisk these ingredients together until they are fully blended and create a cohesive sauce.
Add the cooled, cooked noodles to the bowl containing the sauce. Gently toss the noodles with the sauce until they are evenly coated, ensuring every strand is infused with flavor.
Add the shredded carrots, julienned cucumber, and thinly sliced red bell pepper to the noodles. Stir carefully to incorporate the vegetables, ensuring they are well dispersed amongst the noodles.
Top the noodle mixture with toasted sesame seeds and slices of green onions, seasoning with salt to taste.
Give everything a final, gentle toss to ensure all ingredients are harmoniously combined.
Serve the spicy noodle bowls in individual serving bowls, garnishing each with a generous handful of fresh cilantro or basil for a bright, aromatic finish.
Notes
Adjust the chili garlic sauce based on your spice tolerance.
