Cut the cauliflower into florets and rice using a food processor (or grate the cauliflower).
Heat the butter in a frying pan and cook the cauliflower for 5-8 minutes.
Add the kale and cook until the kale is soft.
Remove the pan from the heat.
Add the ½ cup (50g) of the Parmesan cheese, beaten egg, garlic powder, salt and pepper.
Mix well until all the ingredients are combined.
Place the remaining Parmesan cheese on a plate.
With your hands (clean and slightly damp) make the croquette shapes by hand.
Roll the croquettes into the plated Parmesan to give them a coating.
Place the croquettes onto parchment/baking paper and put into the fridge for about 1 hour to firm up.
Preheat the oven to 200C/400 degrees
Bake the croquettes for 25 minutes, turning over halfway through so that they are evenly brown.
Eat and enjoy!
