Cut the chicken breast fillets in half and season both sides with salt and pepper.
Heat 2 tablespoons oil in a pan over medium-high heat.
Fry the chicken 4-5 minutes on each side until cooked through (internal temperature 74°C / 165°F).
Remove the chicken and set aside to keep warm.
While the chicken rests, prepare vegetables: cut carrots into thin strips, roughly chop sugar snap peas, cut zucchini into strips, mince garlic, roughly chop pak choi, and finely chop the chilli pepper.
Heat the remaining 4 tablespoons oil in a non-stick pan over medium-high heat.
Add all prepared vegetables and cook for 6 minutes, stirring frequently.
Pour in the orange juice, apple cider vinegar, and water.
Season with turmeric, paprika powder, salt and pepper to taste.
