Before you start

Preheat the oven to 240C / fan 220C / gas mark 9 / air fryer 200C
Line 2 baking trays with parchment paper
Pull out a large frying pan, a measuring jug & a grater

Get started

Remove the steaks from the fridge and allow to come to room temperature. Season both sides with salt and pepper
Cut the potatoes into chips. Place onto a lined baking tray and toss with 1 tbsp oil and a pinch of salt and pepper. Roast for 20 mins / air fryer 15 mins
Meanwhile, trim the broccoli. Finely dice the shallot. Finely chop the chives. Finely grate the cheese

Sizzle the steaks

Heat the large frying pan with 2 tsp oil on medium-high heat. Once hot, add the steaks and cook (as a guide: cook for 3-4 mins on each side for medium-rare, or 6-7 mins for well done). Quickly sear the edges of the steaks, then cover to keep warm and leave to rest

Roast the greens

After 20 mins, add the broccoli and sugar snaps to the other lined baking tray. Drizzle with 1 tsp oil and a pinch of salt and pepper. Roast for a further 9-10 mins / air fryer 5-6 mins, until soft and golden

Sauce time

Reheat the large frying pan with 1 tsp oil on medium heat. Once hot, add the shallot and a pinch of salt and cook for 3-4 mins, until softening
Add half the vinegar and cook for 30 secs, then add the stock, mustard, half the cheese and 200ml water. Simmer for 2-3 mins, until thickened
Stir in half the chives, then remove from the heat. Season to taste with salt and pepper. Add a splash of water if it's too thick

Finish & plate up

When ready, toss the greens with the sumac, remaining vinegar and remaining chives
Slice the steaks against the grain
Serve the steaks onto plates, drizzled with the sauce. Serve the greens and chips alongside. Sprinkle the truffle zest (use less for a milder flavour) and remaining cheese over the chips to finish
