Instructions

1. Step 1: For pickled onions, combine 1/2 cup white vinegar, 1 tbsp sugar, and 1/2 cup water in a small saucepan; bring to a simmer over medium heat until sugar dissolves. Place 1/2 medium thinly sliced red onion in a jar and pour the hot vinegar mixture over it; let cool and refrigerate for at least 30 minutes.
2. Step 2: Heat a large skillet over medium-high heat and add 1 lb ground beef, 1 small finely chopped yellow onion, and 3 minced garlic cloves; cook, breaking up the meat with a spoon, until beef is browned and onions are soft, about 7 minutes.
3. Step 3: Stir in 2 tsp chili powder, 1 tsp ground cumin, 1/2 tsp smoked paprika, 1 tsp salt, 1/2 tsp black pepper, and 1 cup cooked pinto beans; cook for 5 more minutes until heated through and flavors meld.
4. Step 4: Warm 8 small corn tortillas by heating them in a dry skillet over medium heat for 30 seconds per side until pliable and slightly toasted.
5. Step 5: Assemble tacos by spooning the beef and bean mixture evenly onto tortillas, topping with pickled red onions and 1/4 cup chopped fresh cilantro leaves; serve with lime wedges for squeezing.
