In this delicious riff on a quesadilla, eggs are lightly scrambled, then a corn tortilla is pressed onto them and they're cooked further with grated cheese. Slideshow: More Brunch Recipes
In a small bowl, mix the sour cream with the cumin and season with salt. In a 6-inch skillet, heat the olive oil. Add the eggs and cook over moderate heat without stirring, until set at the edges, about 1 minute. Place the tortilla over the eggs, press gently and cook until the eggs are just set, about 2 minutes. Flip the eggs and tortilla and sprinkle on half of the cheese. Cook until the tortilla is golden on the bottom, about 2 minutes. Slide the tortilla onto a plate. Top with the remaining cheese and garnish with chives and olives. Serve with a dollop of the cumin sour cream.
