Heat the oil in a large skillet over medium heat. Add the onion, garlic and a pinch of salt letting the onion sweat a bit while you prepare the sweet potato.

Cut the potato into small cubes so they cook up fast and evenly.

Add the potato to the skillet. Raise the heat and cook until things start to caramelize, about 5 minutes.

Things may start to stick a bit. That's OK. Add about ½ cup of water and scrape the bottom of the pan. This will help get all that flavor up and soften the potatoes.

While the water is cooking down, chop the kale and add it to the skillet.

Mix everything together and lower back down to medium heat.

Chop the mushrooms. Add them to the pan and continue to cook until they soften.
