Preheat the boiling Stove top.
Prepare the garlic butter. In a small bowl, combine the butter, the garlic and lemon zest, salt and pepper. Stir until smooth . keep aside until needed.
Heat the griddle pan on the boiling stove top until smoking hot. ( you can preheat the griddle pan in the roasting oven if the stove top is busy.)
Brush the steaks with a little oil on both sides and season with some salt and pepper. Add the steaks, do not move for at least 2 minutes. Turn the steaks over and cook for a further 3 minutes for rare. Turn the heat of and add half of the garlic butter in the pan. Let the butter melt and using a spoon baste the steak with the butter to coat all the flavour over the meat. Leave aside for a minute or so to rest.
In the meantime, place some salad leaves in a bowl. Add the cherry tomato and shallot. Add a good squeeze of lemon juice and some olive oil. Toss to combine.
Carve each steak and spoon extra garlic butter over the steaks to melt and serve with the salad and baked potatoes.
