Preheat oven to 375 degrees F. Coat the bottom of a baking dish with a thin layer of the sauce; set aside.
Heat a nonstick pan over medium heat; add the ground beef and season with salt and pepper. Cook until browned, about 3-5 minutes, making sure to crumble the beef as it cooks; then drain the excess fat.
Mix the beef and 1/2 of the cheese's.
To assemble the enchiladas, lay the tortillas on a flat surface and spoon the beef mixture in the center. Roll the taco shells and place them seam side down into the prepared baking dish. Top with remaining enchilada sauce and cheese's.
Place into oven and bake until the cheese has melted, about 10 - 15 minutes.
Serve immediately, with shredded lettuce, tomato, sour cream. Garnish with cilantro.
