01 - Divide the ground beef into 8 equal portions and roll into balls. Season each ball evenly with smoked paprika, garlic powder, salt, and black pepper.
02 - Heat a large skillet or griddle over medium-high heat and add a light coating of vegetable oil.
03 - Place 2 seasoned beef balls onto the hot skillet. Press each one down firmly with a spatula to form thin, even patties.
04 - Cook the patties for 2 minutes until the edges turn crispy. Lay a slice of cheddar cheese on each patty, then place a flour tortilla on top. Press lightly so the cheese bonds to the tortilla.
05 - After 1 to 2 minutes, carefully flip each patty and tortilla together so the tortilla sits directly on the skillet. Toast for 1 minute until golden and crispy.
06 - Remove the finished tacos from the skillet and repeat the process with the remaining beef balls, cheese slices, and tortillas. Add more oil as needed.
07 - In a small bowl, whisk together the mayonnaise, ketchup, and hot sauce until smooth and well combined.
08 - Top each taco with sliced red onion, diced tomato, shredded lettuce, pickled jalapeños, a dollop of sour cream, and a drizzle of the spicy sauce. Fold and serve immediately.
