In a blender or food processor, add all chicken marinade ingredients (vegetable oil, soy sauce, fish sauce, sesame oil, brown sugar, garlic, lemongrass, and onion) and mix for 1 minute until smooth.

Place cubed chicken into a large mixing bowl and pour the marinade on top. Toss well to coat. Cover and refrigerate for at least 1 hour (or overnight for the best results). You can also store the marinated chicken in a sealable ziploc bag.

You can grill, bake, or air fry the chicken skewers.

To grill the skewers: Thread 4-5 pieces of cubed chicken onto bamboo skewers. Lightly apply cooking oil over chicken skewers using a cooking oil spray or silicone brush. Preheat the grill over medium-high heat for 3 minutes until sizzling hot. Place the skewers evenly apart on the grill pan and grill for 8-10 minutes on each side, or until the internal temperature of the chicken reaches 165 F. Do not overlap the skewers at any time to ensure even cooking for all the skewers.

To bake the skewers: Preheat the oven to 425 F. Place the marinated chicken skewers on a parchment-lined baking sheet or on a lightly oiled roasting rack in a baking pan. Bake for 15 minutes until golden brown and the internal temperature for the chicken reaches 165F. Turn on the broil function on the oven on high and broil for 2-3 minutes until nicely charred on the edges.

To cook in the air fryer: Do not thread them and place about 10 cubed chicken pieces in the air fryer basket at a time. Cook at 350 F for 25 minutes, shaking the basket halfway through.

Bring a medium pot of water to a boil. Add vermicelli noodles and cook for 2-3 minutes until they are soft. Use a strainer to transfer the noodles into a medium mixing bowl and set aside.

Assemble the noodle bowls by placing 1.5 cups (2 oz.) of cooked vermicelli noodles into each serving bowl. Top with sliced chicken, cucumber, carrots, cilantro, and peanuts.

Combine all the sauce ingredients into a small mixing bowl. Stir well with a spoon until smooth and sugar is dissolved. Pour the sauce over the noodle bowls and drizzle with extra lime juice, if desired.
