Bread sauce

Heat 1 tsp oil in a large lidded frying pan over a medium heat. Arrange the lettuce halves in the pan, cut-side down, and fry for 2 mins until beginning to brown. Pour in the stock, cover with the lid and cook for 6 mins.

Meanwhile, season the salmon with a good pinch each of salt and pepper on both sides of the fillets. Heat the remaining oil in a second pan over a medium heat and fry the salmon, skin-side down, for 3 mins. Carefully flip using a fish slice and cook for 3 mins more until cooked through and the flesh easily flakes.

Tip the peas and dill into the pan with the lettuce and cook for 2 mins, covered, until the lettuce is tender but still retains its structure. Arrange the salmon fillets and lettuce halves on serving plates.

Stir the crème fraîche and mustard into the lettuce pan and cook over a low heat to warm through. Pour the sauce and peas over the lettuce and salmon.
