Heat a large skillet over medium heat and add the olive oil, allowing it to warm until shimmering.
Add the diced sweet potatoes to the pan in an even layer. Cook without stirring for about 4-5 minutes until the undersides are golden brown and crispy.
Use a spatula to flip the sweet potatoes carefully, then cook for another 4-5 minutes until they are tender inside and well crispy outside.
Stir in the minced garlic and smoked paprika, cooking for another 1-2 minutes until fragrant and evenly coated on the sweet potatoes.
Sprinkle generously with salt and pepper, adjusting to your taste, then add the chopped greens to the pan. Cook just until wilted—about 1 minute—letting their vibrant color contrast with the crispy sweet potatoes.
Turn off the heat and give everything a final gentle fold to combine the flavors and textures. Serve immediately for the best crispy and tender contrast.
