Preheat oven to 400 degrees F.

Combine lettuce, scallion, cilantro, 1 teaspoon oil, lime juice, 1/8 teaspoon salt and 1/8 teaspoon pepper in a bowl; set aside. Combine beans and salsa in another bowl.

Coat both sides of each tortilla with cooking spray. Place tortillas on a large baking sheet in 4 sets of overlapping pairs. (Each pair should overlap by about 3 inches.) Spread about 1/3 cup of the bean mixture on top of each pair of tortillas and sprinkle with 3 tablespoons cheese each. Bake until the beans are hot and the cheese is melted, about 10 minutes.

Meanwhile, heat the remaining 2 teaspoons oil in a large nonstick skillet over medium heat. Crack each egg into a small bowl and slip them one at a time into the pan, taking care not to break the yolks. Season the eggs with the remaining 1/8 teaspoon salt and pepper. Reduce heat to medium-low and cook undisturbed for 5 to 7 minutes for soft-set yolks. (For hard-set yolks, cover the pan after 5 minutes and continue cooking until the yolks are cooked through, 4 to 6 minutes more.)

To assemble, place an egg on top of each pair of tortillas and top with a generous 1/4 cup of the lettuce mixture.

Tip: Green salsa (sometimes labeled salsa verde or tomatillo salsa) is made with tomatillos, green chiles and onions. Look for it near other prepared salsa in large supermarkets.
