Cook the soba noodles according to the package instructions until al dente. Drain and rinse under cold water to stop the cooking process. Set aside.
In a large skillet, heat the sesame oil over medium heat. Add the minced garlic and grated ginger, sautéing for about a minute until fragrant.
Add the sliced red bell pepper and snap peas to the skillet, cooking for about 3-4 minutes until they are just tender, yet still crisp.
In a small bowl, whisk together the soy sauce, sriracha, and rice vinegar. Pour this mixture into the skillet with the vegetables.
Add the cooked soba noodles to the skillet, tossing everything together to combine and heat through. Make sure the noodles are well-coated in the sauce.
Stir in the chopped green onions and sesame seeds, reserving a little for garnish.
Remove from heat and serve warm, garnished with fresh cilantro and the reserved sesame seeds. Add a lime wedge on the side for a zesty finish.
Notes
Adjust the sriracha to your preferred spice level.
