In a large skillet over medium heat, add 1 tablespoon of olive oil. Once hot, add the ground beef and cook until browned, breaking it apart with a spatula, about 5-7 minutes.

Add Onion and Garlic

Chop the onion and mince the garlic. Add them to the skillet with the ground beef. Sauté for an additional 3-4 minutes until the onion is translucent and garlic is fragrant.

Season the Beef

Sprinkle the taco seasoning over the mixture, stir to combine, and add 1/4 cup of water. Cook for another 5 minutes until the beef is well coated with the seasoning and the water has evaporated.

Prepare the Tacos

Warm the Tortillas

In a dry skillet or on a grill, warm the corn tortillas over medium heat for about 30 seconds on each side until pliable.

Assemble the Tacos

Place a spoonful of the taco filling on each tortilla. Top with shredded lettuce, diced tomatoes, shredded cheese, and a dollop of sour cream.

Garnish and Serve

Sprinkle chopped cilantro on top. Serve with lime wedges on the side and hot sauce to taste.
