Begin by boiling a large pot of water. Once boiling, add the dried udon noodles and cook according to the package instructions, usually around 5-7 minutes. Drain and rinse under cold water to stop the cooking process, then set aside.
In a small bowl, whisk together the tamari or soy sauce, chili paste, rice vinegar, lemon juice, and honey until well combined. This sauce will be the magic that brings all the flavors together.
In a large skillet or wok, heat the toasted sesame oil over medium-high heat. Add the chopped garlic and ginger, sautéing for about 30 seconds until fragrant. Then, add the thinly sliced chicken to the skillet. Cook until the chicken is browned and cooked through, about 5-7 minutes.
Once the chicken is cooked, add the frozen stir fry veggies to the skillet. Stir-fry for an additional 3-4 minutes until the vegetables are heated through and slightly tender.
Add the cooked udon noodles to the skillet along with the prepared sauce. Toss everything together until the noodles and chicken are evenly coated in the sauce and heated through, about 2-3 minutes.
Remove the skillet from heat. Serve the 20 Minute Honey Garlic Chicken Udon Noodles in bowls, garnished with chopped scallions, toasted sesame seeds, and fresh cilantro or Thai basil. Enjoy your quick and delicious meal!
