In a large skillet, heat the vegetable oil over medium-high heat.
Add the chopped onions and minced garlic to the skillet. Sauté for 2-3 minutes until they become fragrant and translucent.
Add the ground beef to the skillet and cook, breaking it apart with a spatula, until it's browned and cooked through. Drain any excess fat if needed.
Sprinkle the ground cumin, chili powder, paprika, salt, and pepper (or use the taco seasoning mix) over the cooked beef. Stir well to evenly coat the beef with the spices. Cook for another 2-3 minutes to allow the flavors to meld. Remove from heat.
Wash and prepare the lettuce leaves. Pat them dry with a paper towel.
To assemble the tacos, place a spoonful of the seasoned beef mixture onto each lettuce leaf.
Top the beef with grated cheese, diced tomato, and a dollop of sour cream.
Add salsa on top for an extra kick.
Garnish with fresh cilantro leaves and serve with lime wedges on the side.
