Two small tortillas sandwiching grilled steak and melted cheese, cooked on a flat griddle. These high protein, carnivore-friendly street food bites are a family taco night favorite.
Thinly slice the flank steak against the grain, then season evenly with salt and black pepper.
Preheat a flat griddle or large skillet over medium-high heat. Add 1 tbsp of vegetable oil.
Sear the steak quickly in the hot oil for 2-3 minutes, stirring to brown all sides. Remove steak to a plate.
Wipe the griddle clean, then lower heat to medium. Add the remaining oil and place half the tortillas down.
Top each tortilla with a layer of cheese, cooked steak, onion, and cilantro, then add more cheese and cover with another tortilla. Press gently.
Cook the assembled mulitas for 2-3 minutes per side, flipping once, until both tortillas are crisp and the cheese is fully melted.
Remove from the griddle, let cool for a minute, then slice in half and serve hot.
