For the marinade, combine the juice of one lemon with garlic paste and parsley in a ziplock bag, then add the flank steak and let it marinate for about an hour.

Meanwhile, dice the red onion, tomato, and parsley, and mix them together in a bowl.

Next, fry the flank steak on high heat with a bit of butter for about 1 minute on each side, then slice it into fillet pieces.

To prepare your tacos, spread cream cheese on the tortillas, then add the steak slices and salad mixture on top.
