Step 1

Heat the oil in a large skillet over medium heat until shimmering. Add the onion, jalapeño, and, garlic, and cook, stirring occasionally, until softened, about 5 minutes. Stir in the cumin, chili powder, oregano, salt, and pepper and cook for 1 minute. Add the tomatoes. Bring to a boil, then reduce the heat to low and simmer for 10 minutes. Meanwhile, heat the oven.

Step 2

Arrange a rack in the middle of the oven and heat to 400°F. Coat a 9x13-inch baking dish with cooking spray; set aside.

Step 3

Arrange 6 of the tortillas in a single layer in the bottom of the baking dish. Spread about 1/2 of the sauce over the tortillas. Sprinkle about 1/3 of the cheese in an even layer over the sauce. Add the beans and spread in an even layer. Sprinkle about half of the remaining cheese over the beans. Top with the remaining tortillas in a single layer. Spread the remaining sauce over top and sprinkle with the remaining cheese.

Step 4

Use the back of a spoon to press down into the top of the casserole to make 10 shallow divots for the eggs. One at a time, crack an egg into a small bowl or ramekin without breaking the yolk, and pour into each of the divots. Sprinkle the eggs with salt.

Step 5

Bake until the egg whites are fully set, 15 to 18 minutes. Cool for 5 minutes. Top with cilantro and avocado, then slice and serve warm.
