Combine spinach, scallions, and cheese in a large bowl. In a separate bowl, beat eggs with salt and pepper. Heat a concave pan, such as a large wok, on medium-low and add about 1 teaspoon clarified butter. Swirl to coat evenly. Place one tortilla in pan and mound half of spinach mixture in the middle. Make an indentation in the center of the mound and pour half of egg mixture into it. Immediately place another tortilla on top and press down, first in center, then all around the edge. The goal is to form a seal by forcing some of the egg to the outer edge, where the heat will cook it and join the two tortillas. Turn heat to low and cook for a minute or two, until edges are sealed and bottom is golden
