Heat your skillet or griddle over medium-high heat and crumble the ground beef into small pieces. Season generously with salt, cumin, chili powder, complete seasoning, and oregano. Let the spices toast in the beef fat.
Once the beef is browned, stir in 1 tbsp soy sauce to deepen the color and flavor. Pour in 1 cup chicken stock and let the beef simmer for about 10 minutes until most of the liquid cooks down and the meat becomes tender and saucy.
Blend jalapeño, cilantro, lime juice, mayo, sour cream, and salt until creamy and smooth.
Heat a thin layer of vegetable oil on your griddle or skillet. Lay down a flour tortilla and sprinkle mozzarella and Monterey Jack on one side. Add a spoonful of beef and fold the tortilla over.
Fry until golden and crispy on one side, flip, and crisp the other until the cheese melts and the tortilla is crunchy.
Pair with the green sauce for dipping or drizzling and enjoy immediately for the best crisp.
