Step-by-step instructions

1. 1

Add the kale and 1 tbsp water, and cook for 5 mins until the kale has wilted. Pour in the balsamic vinegar and bubble for 1 min, then add the eggs. Give everything a quick stir, then leave undisturbed to cook over a low-medium heat for 5 mins until the egg is nearly set and the frittata is turning golden brown on the bottom.
