01 - Preheat the oven to 400°F.
02 - Heat a skillet over medium heat. Add ground beef and cook for 3-4 minutes, breaking up with a spoon.
03 - Add onion and garlic; sauté until the onion is soft and beef is browned, about 3 more minutes. Drain excess fat if needed.
04 - Stir in cumin, smoked paprika, chili powder, salt, and black pepper. Add half the jalapeno slices. Cook for 1-2 minutes for flavors to meld. Remove from heat.
05 - Spread tortilla chips evenly on a large baking sheet or ovenproof platter.
06 - Spoon the cooked beef mixture evenly over the chips.
07 - Sprinkle both cheeses generously over the beef and chips. Add remaining jalapeno slices on top.
08 - Bake in the preheated oven for 7-8 minutes, or until cheese is melted and bubbling.
09 - Remove from oven. Top with diced tomatoes, spring onions, and cilantro. Serve hot with sour cream and lime wedges on the side.
