Ingredients
  

  • 2 sweet potatoes or jewel yams, cut into 1-inch cubes
  • 2 tablespoons olive oil, divided
  • Salt and freshly ground black pepper, to taste
  • 1 onion, sliced
  • 3 cloves garlic, minced
  • 1 bunch kale, torn into bite-sized pieces
  • 2 tablespoons red vinegar
  • 1 teaspoon chopped fresh thyme

Instructions
 

  • Preheat the oven:
    Set your oven to 400°F (200°C) to ensure it’s nice and hot for roasting.
  • Prepare sweet potatoes:
    Toss the sweet potato cubes with 2 tablespoons of olive oil, then season generously with salt and black pepper. Spread them evenly on a baking sheet for even roasting.
  • Roast until golden:
    Slide the sweet potatoes into the preheated oven and bake for 20-25 minutes, turning halfway. They should be tender and slightly caramelized. Let cool to room temperature.
  • Caramelize the onions:
    Heat 1 tablespoon olive oil in a skillet over medium heat. Add the sliced onions and cook for 10-15 minutes, stirring occasionally, until golden and sweet. Add minced garlic in the final 2 minutes of cooking.
  • Wilt the kale:
    Add the torn kale to the skillet with the onions and cook for 2-3 minutes, just until it softens. Transfer the kale mixture to a bowl and allow it to cool.
  • Combine and dress:
    Toss the cooled sweet potatoes, kale mixture, red vinegar, and fresh thyme in a large mixing bowl. Adjust seasoning with salt and pepper to taste.
  • Serve and enjoy:
    Serve immediately or refrigerate for later. This salad is delicious warm or chilled!
