Tarragon and Mustard Fish

Steps

1. Bring a medium pot of salted water to the boil. Prepare ingredients.
2. Cook quinoa in pot of boiling water for about 14 minutes. Add peas to pot and cook a further 1-2 minutes, until peas are bright green and quinoa is tender with a bite. Drain and leave to drain well.
3. While quinoa cooks, prepare broccoli and spinach. Heat oil in a large, non-stick fry-pan on medium-high heat. Cook onion with a pinch of salt for 3-4 minutes, stirring often. Add broccoli, stock/water and salt. Bring to a simmer and cook for 2-3 minutes, until broccoli is tender with a bite. Set aside in a bowl, wipe pan clean and reserve pan.
4. Prepare fish. In a medium bowl, combine mustard, honey, tarragon spice mix and lemon zest and juice to make a paste. Pat fish dry and remove any remaining scales or bones.
5. Heat oil in reserved pan on medium-high heat. Add fish to bowl with paste and toss gently to coat. Cook fish for 2-3 minutes each side (depending on thickness), or until just cooked through. Set aside to rest, wipe same pan clean and reserve.
6. Make lemon yoghurt by whisking together lemon zest and juice, yoghurt and honey (if using) in a small bowl. Season to taste.
7. Return pan to medium heat. Add quinoa and peas, along with cooked broccoli mixture to pan and cook for 1-2 minutes, until heated through. Remove from heat and stir through all remaining broccoli and spinach ingredients just before serving.
8. To serve, pile broccoli and spinach onto plates and top with tarragon and mustard fish. Drizzle over lemon yoghurt.
