Cook the rice noodles according to the package directions. Drain well and set aside.
Heat 1 tablespoon sesame oil in a large skillet over medium heat. Add honey, peanuts, sesame seeds, and chili flakes. Cook for 3–4 minutes until lightly caramelized. Transfer to parchment paper, sprinkle with salt, and cool.
In a bowl, whisk together honey, soy sauce, fish sauce, Thai red curry paste, and ketchup until smooth.
Wipe out the skillet and heat the remaining oil over medium heat.
Add the sliced chicken, season with black pepper, and cook until browned and lightly crispy, about 5 minutes.
Stir in garlic and ginger and cook for another 2–3 minutes.
Pour in one-third of the sauce and cook until it coats the chicken.
Add zucchini and bell peppers. Cook for about 5 minutes until slightly tender.
Add the remaining sauce and bring to a gentle simmer.
Stir in the cooked rice noodles, basil, and cilantro. Toss until everything is evenly coated and heated through. This Saucy Thai Summer Noodle Stir Fry develops even more flavor as the noodles absorb the sauce.
Serve immediately with caramelized sesame peanuts, fresh basil, cilantro, and a generous squeeze of lime.
