Preheat oven to 200°C. Grease a 24cm (base measurement) round fluted quiche dish. Use a mandolin or sharp knife to slice the sweet potatoes crossways into 1mm-thick slices. Place in a large bowl and drizzle with half the oil. Season. Arrange the sweet potato, overlapping slightly, in 3-4 layers over the base and side of the prepared dish, allowing the sweet potato to extend above the side. Place on a baking tray. Bake for 20 mins or until the sweet potato is tender. Reduce oven to 160°C.

Meanwhile, heat the remaining oil in a medium frying pan over medium heat. Add the leek, cut-side down, and cook for 1 min each side or until light golden. Transfer to a plate. Add the spinach to the pan and cook, tossing occasionally, for 2 mins or until spinach just wilts. Transfer to a bowl.

Place baby broccoli, broad beans and the combined peas in a heatproof bowl. Pour over enough boiling water to cover. Set aside for 30 secs. Drain.

Whisk the egg and cream in a large bowl until well combined. Season.

Arrange the spinach, leek, baby broccoli, combined peas, broad beans and goat’s cheese over the sweet potato crust. Pour over the egg mixture. Bake for 30-35 mins or until egg mixture is just set.
