Preheat oven to 180C/ 350F/ GM4 and line a large baking sheet with baking parchment
Mix the paprika, cumin, oregano, thyme, salt and pepper together in a small bowl
Clean the potatoes if necessary, then thinly slice them and lay on the parchment. Scatter the herbs and spices over and toss together with 2 tablespoon olive oil. Roast for 15 minutes
Peel the onion and chop into thick wedges. Crush the garlic cloves with the back of a knife. Deseed and chop the peppers into thick pieces and slice the lemon into quarters. Add these ingredients to the pan once the potatoes have cooked, giving the lemon wedges a quick squeeze to release a little juice before dropping them in. Add the remaining 1 tablespoon of oil, toss everything briefly and cook for 20 minutes
Just before the end of the cooking time, prick the tomatoes with a sharp knife and slice the chorizo & the courgette into ½ cm rounds. Add to the pan, toss briefly and cook for 10 minutes
Finally, rinse and dry the prawns. Devein if necessary and make a slit along the back of each prawn. Add to the pan, toss to pick up the oil and flavours and bake for a final 10 minutes
Check seasoning, adding a little more salt if desired and serve
