Prep time: 10 minutes
Cook time: 20 minutes
Servings: 4
Ingredients:
2 Potatoes, scrubbed and cut into 1/2-inch cubes
about 4 Tablespoons good quality extra-virgin Olive oil, divided, plus more as needed
2 small yellow Onions, chopped
2 cloves Garlic, finely chopped
1 1/2 teaspoons dried Oregano
1/2 teaspoon dried Red Chili flakes
1/2-1 pound Mushrooms, thinly sliced
1 bunch Kale leaves, stems removed, leaves chopped
1 pinch Salt to taste
1 pinch Freshly ground Pepper to taste
Directions:
1. Put the potatoes in a medium saucepan. Cover with water and a generous pinch of salt. Bring to a boil and simmer until cooked through, about 8 to 10 minutes. Drain well.
2. Heat 2 tablespoons of the oil in a large skillet over medium-high heat. Add the onions and cook until softened and browned, about 5 minutes.
3. Add the garlic, oregano, and chili flakes, cooking an additional 1-2 minutes until fragrant.
4. Add additional olive oil to coat the bottom of the pan. Bring to high heat. Add the potatoes. Let cook for a few minutes, stirring infrequently, so the potatoes can brown (it is okay if they mash).
5. Add the mushrooms, and continue to cook until they start to brown, adding additional olive oil as needed.
6. Add the kale and cover with a lid, letting cook for a few additional minutes until wilted.
7. Sprinkle with salt and pepper to taste.
8. Serve warm.
