Step 1

Heat the oven to 220C/200C fan/gas Combine the tomatoes, stock, paprika and saffron in a large heatproof jug, then microwave for 5 mins on high, or until steaming hot. Or, heat in a pan on the hob.

Step 2

Put the onion and garlic in a large ovenproof frying pan or roasting tin, drizzle over the olive oil and stir to coat. Roast for 20 mins, or until the veg is starting to brown.

Step 3

Stir in the rice, chicken, chorizo and hot stock mix. Season and bake for 20 mins (don’t cover the pan).

Step 4

Gently stir in the peas, dot over the prawns and press the mussels in, hinged-side down, so they’re standing up. Arrange the lemon wedges around the edge, if using. Bake for 5-10 mins more until the rice, chicken and prawns are cooked, and the mussels have opened (discard any that stay shut). Check for seasoning, and serve.
