Chop 1/2 an onion. In a shallow pan add some EVOO and the garlic powder – warm over a medium heat. Once the pan is hot add the onion and fry until softened (about 3-5 minutes). Next add the sweet potato to the pan and fry for a few more minutes.
Finally add the kale and allow it to wilt. Lightly season the veggies with salt & pepper. If you’re using cheese add it now and mix it all up.
Prepare a muffin tin with 12 baking paper liners. Add the veggie mixture to the bottom of the liners and press down so the base is nice and compact. The liners should be about half-way full. Next crack 1 whole egg over each veggie mixture. Add a dusting of salt & pepper to the top of each egg cup.
Pop in the oven until the whites and yolks are no longer runny – should take about 20 minutes. They may puff up a bit and get some bubbles, this is not a problem.
Allow to cool & enjoy! Store leftovers in the fridge for 3 days
