Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Toss 2 large sweet potatoes, diced into 1/2-inch cubes, with 2 tbsp olive oil, 1/2 tsp ground cumin, 1/2 tsp smoked paprika, and 1/4 tsp salt. Spread on a baking sheet and roast for 20 minutes until tender and slightly crispy.
  2. Step 2: While potatoes roast, heat a small skillet over medium heat. Add 1/4 cup red onion, finely chopped, and 1 jalapeño, minced, and cook for 3 minutes until softened.
  3. Step 3: Add 1 can black beans, 1/2 cup corn kernels, and 1/4 cup lime juice to the skillet. Cook for 5 minutes until heated through and flavors meld, stirring occasionally.
  4. Step 4: Warm tortillas in a dry skillet for 30 seconds per side until pliable.
  5. Step 5: Assemble tacos by placing roasted sweet potatoes and black bean mixture on each tortilla, then top with 1/4 cup shredded purple cabbage, 2 slices avocado, and 1 tbsp fresh cilantro.
