Drizzle olive oil over kale in a large bowl. Massage kale to coat well in oil; this also helps to soften the kale. Spread half the kale over the tray.

Bake frittata for 1 hour or until set; bake kale for 5 minutes or until crisp. Leave frittata in dish for 10 minutes before serving.

Step 5

Meanwhile, make green sauce.

Step 6

Serve frittata topped with roast kale and green sauce. Sprinkle with extra parsley leaves and dill, if you like.
