Preheat the oven to 180°C and bake the chicken skewers for 15-18 minutes, or grill for a charred finish.
In a saucepan, bring the water or stock to a boil, add the quinoa, and simmer for 12-15 minutes until fluffy. Stir in the black beans, cumin, olive oil, lime juice, and chopped coriander. Season to taste.
To make the salsa verde, blend the parsley, coriander, garlic, green chilli, capers, vinegar, olive oil, lemon juice, and salt until smooth. Adjust seasoning if needed.
Serve the chicken skewers over a bed of quinoa and black beans, drizzled with salsa verde. Garnish with extra coriander and a wedge of lime.
