Heat a large skillet or griddle over medium-high heat for about 2 minutes. Add the oil.
Add the diced onion and cook for 3 minutes until softened.
Stir in the garlic, jalapeño, and green bell pepper. Cook for another 2 minutes.
Push the vegetables to one side of the skillet. Add the ground beef in small loose portions onto the hot surface.
Sprinkle the coffee granules, cardamom, cinnamon, nutmeg, smoked paprika, salt, black pepper, and baking powder over the meat.
Smash the beef flat with a spatula so it cooks in a thin layer, then gently mix it with the vegetables.
Let the meat cook undisturbed for 3 to 4 minutes so it develops a deep crust.
Break up the beef and continue cooking for 2 to 3 more minutes, until no pink remains.
Warm the tortillas on the empty side of the griddle or in a dry skillet for about 45 seconds per side.
To assemble the Dubai Taco Recipe, place a warm tortilla on a plate and add a generous layer of shredded Monterey Jack cheese down the center.
Spoon the hot beef mixture over the cheese.
Top with chopped cilantro, a squeeze of lime, and sour cream or labneh. Serve immediately.
