In a medium bowl, combine the chicken strips, cornstarch, soy sauce, lime juice, neutral oil, garlic powder, salt, and pepper. Toss until the chicken is evenly coated. Let the chicken marinate at room temperature for 15–20 minutes while you prepare the sauce and vegetables.
Heat the olive oil and sesame oil in a large deep skillet or wide saucepan over medium heat. Add the diced onion and cook, stirring occasionally, for 4–5 minutes or until softened and translucent.
Stir in the minced garlic and grated ginger and cook for 30–60 seconds, just until fragrant. Sprinkle in the curry powder, ground cumin, paprika, turmeric, and red pepper flakes. Cook, stirring constantly, for about 30 seconds to bloom the spices.
Pour in the chicken broth, scraping up any browned bits from the bottom of the pan. Stir in the coconut milk, brown sugar, and soy sauce. Bring the mixture to a gentle boil, then reduce the heat to medium-low and simmer for 10–12 minutes, stirring occasionally, until slightly thickened and flavorful.
Whisk in the peanut butter until the sauce is completely smooth and creamy. Stir in the lime juice and rice vinegar. Taste the sauce and adjust seasoning with additional salt, lime juice, or red pepper flakes as desired. Reduce the heat to low to keep the sauce warm while you cook the chicken.
In a separate large skillet, heat a thin layer of neutral oil over medium-high heat. Add the marinated chicken in a single layer, working in batches if needed to avoid crowding the pan. Sear the chicken for 3–4 minutes per side, or until golden brown and cooked through (165°F internal temperature). Transfer cooked chicken to a plate and repeat with any remaining chicken.
Return the coconut curry sauce to a gentle simmer over medium heat. Add the julienned carrot and zucchini and cook for 3–4 minutes, or until the vegetables are crisp-tender.
Stir in the thawed peas and the cooked chicken, along with any accumulated juices from the plate. Toss gently until the chicken and vegetables are warmed through and evenly coated in the sauce. Adjust seasoning again if needed.
To serve, spoon hot jasmine rice into bowls or onto plates. Top with generous scoops of the coconut curry bang bang chicken and vegetables. Garnish with chopped peanuts, green onions, toasted sesame seeds, and optional cucumber slices and cilantro. Serve with lime wedges for squeezing over the top.
Serve immediately while hot and creamy. Store leftovers in an airtight container in the refrigerator for up to 3 days and reheat gently over low heat, adding a splash of broth or water if needed to loosen the sauce.
