Soak the raw cashews in hot water for at least 30 minutes, then drain and rinse thoroughly.
Cut the chicken breast into bite-sized cubes and thread them onto wooden or metal skewers.
Brush the chicken skewers with olive oil and season evenly with 0.25 tsp sea salt and the black pepper.
Grill the skewers over medium-high heat for 4 to 5 minutes per side until the chicken is golden brown and cooked through.
In a high-speed blender, combine the soaked cashews, water, lemon juice, nutritional yeast, garlic powder, and the remaining 0.25 tsp sea salt.
Blend on high until the mixture reaches a completely smooth and velvety consistency.
Transfer the dip to a small bowl and stir in the finely chopped fresh chives and dill.
Slice the cucumber and carrots into long, thin sticks for dipping.
Serve the warm grilled chicken and fresh vegetable sticks alongside the creamy herb dip.
