Speedy Lamb "Roast"

While the potato is boiling, ribbon your zucchini with a vegetable peeler or thinly slice them lengthways. Get out a grill pan and place on high heat (if you don't have one a normal pan will do). Toss the zucchini with a drizzle of olive oil and to your pan until charred on each side, about 2 minutes per side. Place in a bowl and season to taste with salt and pepper. Keep that pan for your lamb.
