Ingredients

• 1 lb ground beef
• 1/3 cup fresh cilantro, chopped
• 2 tbsp lime juice
• 1 tsp garlic powder
• 1 tsp ground cumin
• 1 tsp salt
• 1/2 tsp black pepper
• 8 small corn tortillas
• 1/2 medium red onion, thinly sliced
• 1/2 cup white vinegar
• 1 tbsp sugar
• 1/2 cup water
• 1 medium ripe avocado
• 1/4 cup sour cream
• 1/4 tsp salt (for crema)

Instructions

1. Step 1: Prepare pickled onions by combining 1/2 cup white vinegar, 1 tbsp sugar, and 1/2 cup water in a small bowl. Stir until sugar dissolves, then add 1/2 thinly sliced red onion. Let sit at room temperature for at least 20 minutes.
2. Step 2: In a medium bowl, mix 1 lb ground beef with 1/3 cup chopped fresh cilantro, 2 tbsp lime juice, 1 tsp garlic powder, 1 tsp ground cumin, 1 tsp salt, and 1/2 tsp black pepper until well combined.
3. Step 3: Heat a large skillet over medium-high heat. Add the beef mixture and cook, breaking it apart with a spoon, for 7-8 minutes until browned and cooked through.
4. Step 4: While the beef cooks, make the avocado crema by blending 1 medium ripe avocado, 1/4 cup sour cream, and 1/4 tsp salt in a food processor or blender until smooth; set aside.
5. Step 5: Warm 8 small corn tortillas in a dry skillet over medium heat for about 30 seconds per side until pliable and slightly toasted.
6. Step 6: Assemble tacos by dividing the cooked beef evenly among the tortillas, topping with pickled onions and a generous drizzle of avocado crema before serving.
