01 - In a mixing bowl, combine diced tomatoes, red onion, jalapeño, cilantro, lime juice, salt, and pepper. Mix well and set aside to let flavors meld while preparing the beef filling.
02 - Heat olive oil in a large skillet over medium heat. Add onion and sauté for 2–3 minutes until softened and translucent. Stir in garlic and cook for 30 seconds until fragrant.
03 - Add ground beef to the skillet, breaking it up with a spatula. Cook until browned and cooked through, about 5–7 minutes. Drain excess fat from the pan.
04 - Sprinkle chili powder, cumin, smoked paprika, salt, and black pepper over the beef. Stir to coat evenly and cook for 1 additional minute to meld flavors. Remove from heat.
05 - Heat mini tortillas in a dry pan over medium heat for 15–20 seconds per side until warm and pliable, or microwave in batches for 15–20 seconds.
06 - Spoon approximately 1 tablespoon of seasoned beef onto each tortilla. Top with shredded cheese, lettuce, and a generous spoonful of fresh salsa. Add sour cream or avocado slices if desired.
07 - Arrange mini tacos on a serving platter and serve immediately while warm. Pair with lager or margaritas for a complete game day experience.
