Boil a pot of water and cook the udon noodles according to package instructions. Once cooked, drain and set aside.
In a large pan or wok, heat the vegetable oil over medium heat. Add the minced garlic, sliced chilies, and grated ginger. Sauté for about 1-2 minutes until fragrant but not browned.
Toss in the bell pepper and snow peas. Stir-fry for an additional 3-4 minutes until the vegetables are tender yet still crisp.
Add the drained udon noodles to the pan with the sautéed vegetables. Pour in the soy sauce, sesame oil, rice vinegar, and honey or maple syrup. Toss everything together gently, ensuring the noodles are coated in the sauce. Stir-fry for another 2-3 minutes.
Once everything is well combined and heated through, remove from heat.
Serve the Chili Garlic Udon hot, topped with chopped green onions and a sprinkle of sesame seeds.
Notes
Adjust the number of chilies based on your spice preference.
