Heat 0 cm of vegetable oil in an 20 cm skillet over medium heat, just until hot. Cook the tortillas, one at a time, in the oil until crisp, about 1 minute.

Line the bottom of an ungreased square 8 X 8 X 5 cm pan with the tortilla chips or pieces. Spread the spinach mixture over them. Cut the eggs lengthwise into halves and arrange them on the spinach mixture.
