Ingredients

Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add 1 1/2 cups corn kernels, 1 cup drained black beans, 1 tsp ground cumin, 1 tsp chili powder, and 1/2 tsp salt. Sauté for 5-7 minutes until the corn is slightly charred and beans are heated through, stirring occasionally.
  2. Step 2: In a small bowl, whisk together 1/4 cup sour cream, 1/4 cup chopped fresh cilantro, and 2 tbsp lime juice until smooth and creamy. Set aside for flavors to meld.
  3. Step 3: Warm 8 small corn tortillas in a dry skillet over medium heat for about 30 seconds per side until pliable and lightly toasted.
  4. Step 4: To assemble each taco, spoon the smoky corn and black bean mixture evenly onto the tortillas. Top with diced 1/4 cup red onion, diced 1 avocado, and drizzle generously with the cilantro lime sauce. Serve immediately for fresh contrast and vibrant flavor.
