In large skillet heat olive oil over high heat. Saute potatoes, shaking the pan frequently, until golden brown, about 5 -7 minutes. With slotted spoon transfer to a mixing bowl. In same skillet saute onions, about 5 minutes. Add garlic and saute for another minute. Add tomatoes, oregano, and cook an additional minute. Remove from heat and stir in olives. Add mixture to mixing bowl. Add pepper. Stir well to combine and set aside.
Heat the grill or preheat oven to 450 degrees. In another skillet, heat vegetable oil until hot, but not smoking. Using tongs, dip each tortilla in the oil, and cook for about 30 seconds each side. Drain on a paper towel. Season fish fillet with salt and pepper. On tin foil, arrange 3 tortillas so they overlap in the center to form a triangle. Place fish fillet in the center. Divide potato mixture into 6 parts and mound 1 portion evenly over the fillet. Fold over tortillas to enclose the stuffing, forming a triangle. Wrap the fish in tin foil. Repeat the wrapping and mounding process with the remaining fillets. To grill, cook 9 minutes on each side on a moderately hot spot on the grill. To bake, place the packets directly on the oven rack and cook for 20 - 25 minutes.
To serve, unwrap and discard the foil and, with a spatula, transfer the fish to plates. Open the tortillas to resemble the leaves of a flower. Though they can be eaten, the real purpose of the tortillas is to add moisture and flavor. Serve with lime wedges as garnish.
In large bowl combine all ingredients and stir until smooth. The dough should be slightly sticky and form a ball when pressed together. To test, flatten a small of dough between your palms. If the edges crack, add water to the dough, a tablespoon at a time, until a test piece does not crack. Divide the dough into 24 golf ball size pieces for tacos and 23 large bowls for quesadillas. Place on a platter and cover with a damp towel. Toast or fry as desired.
