Preheat the oven to 180 degrees (200 if not fan assisted). Then finely chop the onion.
Heat 1 tbsp of olive oil in an oven proof pan and fry the onion for 5 mins.
Then add the chipotle, smoked paprika, broccoli, pasta and veg stock. Mix together and put in the oven for 10 minutes.
Remove from the oven. Add the herbs, lemon zest and peas. Mix together. Then add the fish fillets to the mixture. Sprinkle with a pinch of salt, black pepper, a very light dusting of cayenne pepper and a drizzle of olive oil. Return to the oven for another 10 minutes.
Remove from the oven. Squeeze half the lemon over the top of the mixture and serve.
