If using wooden skewers, soak them in water for at least 20 minutes to prevent burning.
In a small bowl, whisk together the chili garlic sauce, tamari, toasted sesame oil, honey, and minced garlic until well combined.
Pat the shrimp dry with paper towels, season with sea salt and black pepper, and toss with half of the prepared chili-garlic sauce.
Thread the shrimp onto the skewers and set aside to marinate for 10 minutes.
Bring a pot of water to a boil and cook the soba noodles according to package directions, adding the sugar snap peas during the last 60 seconds of boiling.
While the noodles cook, grill the shrimp skewers over medium-high heat for 2 to 3 minutes per side until they are opaque and slightly charred.
Drain the noodles and snap peas, then toss them with the remaining sauce and diced red bell pepper.
Divide the noodle mixture into a bowl, top with the grilled shrimp skewers, and garnish with sliced green onions and sesame seeds.
