STEP 1

Heat oven to 200C/180C fan/gas 6. Mix together 1 tbsp oil, the mustard, honey and some seasoning. Put the salmon fillets on a baking tray and spread the honey and mustard mixture all over. Tip the lentils and beetroot into a casserole dish, toss with the remaining oil and season well. Put both in the oven for 10 mins until the salmon is cooked through.
