Line a baking tray with foil and place the potatoes on it. Drizzle them with olive oil and season with salt.
Bake in the oven for 30 minutes until soft and starting t brown
Remove from the oven and using a folk, press down firmly on the top of each potato so you smash it slightly, but not completely. ( you still want them to hold their form)
Drizzle with a little olive oil then add a small dollop of mustard on top of each one, then layer some rocket and sour cream and finish with a sprig of thyme, salt and pepper.
