Ridiculously easy. Cut round steak into cubes. I use Touchstone Black Angus. Toss in flour, brown. Put into a slow cooker, toss in some taco seasoning (yep), a bit of water, and simmer away. Warm a corn tortilla, fill with meat and a combination of cheddar and cojita cheese. Roll, cover with sauce from the slow cooker. Garnish with diced onions, jalapeno, cilantro, more cojito cheese, and hot sauce.
