Ingredients

• 1 lb ground beef
• 1 tbsp olive oil
• 2 tsp ground cumin
• 1 tsp chili powder
• 1/2 tsp garlic powder
• 1 tsp salt
• 1/2 tsp black pepper
• 1 small, finely chopped yellow onion
• 1 small, thinly sliced red onion
• 1/2 cup white vinegar
• 1 tbsp sugar
• 1/2 cup water
• 8 small corn tortillas
• 1/4 cup chopped fresh cilantro
• 4, for serving lime wedges

Instructions

1. Step 1: In a small bowl, combine 1/2 cup white vinegar, 1 tbsp sugar, and 1/2 cup water, stirring until sugar dissolves. Add 1 small thinly sliced red onion, toss to coat, and let sit for at least 15 minutes to quick pickle.
2. Step 2: Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add 1 small finely chopped yellow onion and sauté for 3 minutes until translucent.
3. Step 3: Add 1 lb ground beef, 2 tsp ground cumin, 1 tsp chili powder, 1/2 tsp garlic powder, 1 tsp salt, and 1/2 tsp black pepper to the skillet. Cook, breaking up the meat with a spoon, for 7-8 minutes until browned and cooked through.
4. Step 4: Warm 8 small corn tortillas in a dry skillet or microwave until pliable.
5. Step 5: To assemble, spoon the cumin-spiced beef onto each tortilla, top with pickled red onions, 1/4 cup chopped fresh cilantro, and serve with lime wedges for squeezing over the tacos.
