Instructions

Step 1: Combine 1/2 cup white vinegar, 1/2 cup water, and 1 tbsp sugar in a small bowl. Stir until sugar dissolves, then add 1 medium thinly sliced red onion. Set aside to pickle for at least 20 minutes.
Step 2: Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add 1 lb ground beef and cook, breaking up with a spoon, until browned and cooked through, about 7-8 minutes.
Step 3: Stir in 2 tsp chili powder, 1 tsp ground cumin, 1 tsp smoked paprika, 1/2 tsp garlic powder, 1/2 tsp onion powder, 1 tsp salt, and 1/2 tsp black pepper. Cook for 2 more minutes until spices are fragrant and beef is well coated.
