Marinade the fish in the given ingredients and keep aside.

Add all the ingredients for mango salsa in a bowl and stir to combine well. Keep aside.

Shake the excess marinade off the fish, save the rest of the marinade. Cook on a skillet at medium-high heat for 3-4 mins on each side or until well cooked. Take it off heat, let it cool and then flake it.

Yoghut-lime sauce:

To the remaining fish marinade, add yoghurt, jalapeno and garlic and stir well. Season with salt and pepper.

To serve:

Heat corn tortillas. Put some flaked fish in the center. Top with mango salsa and finish with some yoghurt-lime sauce.
