Chop lettuce, tomatoes, and cilantro; shred cheese and set aside.

Heat 1 tablespoon olive oil in a skillet over medium heat (about 350°F) until shimmering, about 1 minute.

Add 1 pound ground beef or turkey to the skillet and cook over medium heat, breaking it up, until browned and fully cooked, about 5-7 minutes.

Sprinkle 1 packet taco seasoning over the meat, add 1/4 cup water, stir to combine, and simmer until sauce is reduced, about 2-3 minutes.

Wrap 8 soft taco tortillas in foil and warm in a 350°F oven for 5 minutes or microwave for 30 seconds.

Place a warm tortilla on a plate and spoon about 1/4 cup of seasoned meat onto the center.

Top each taco with shredded lettuce, diced tomatoes, shredded cheese, a dollop of sour cream, and a sprinkle of cilantro.

Arrange tacos on a serving platter and serve immediately while warm.
