Heat the oil in a large saucepan over a high heat. Cook onion, stirring occasionally, for 5 minutes or until softened. Add the garlic and chilli and cook stirring for 1 minute or until fragrant.

Add quinoa and stock and bring to the boil. Reduce heat to low, cover and simmer for 12 minutes, or until stock has almost evaporated. Add broccoli, corn and black beans and stir to combine. Cover and cook for a further 2-3 minutes or until stock has evaporated. Remove from heat and set aside, covered, to steam for 3-4 minutes.

Stir through the spinach. Season with freshly ground black pepper. Top with pepitas, herbs and sliced chilli and serve with lime wedges.
