Heat 1 teaspoon olive oil in a small saucepan over medium heat. Sauté diced onion and minced garlic, stirring occasionally until softened, about 5 minutes. Add black beans, cumin, salt, and water. Stir frequently, cooking until beans are warmed through. Mash at least half the beans with a potato masher or fork and cook a few more minutes until thickened.

Warm 1 tablespoon olive oil in a large skillet over medium-low heat. Fry each tortilla until golden brown and crispy on edges, then flip. Sprinkle a quarter of the cheese over the tortilla and allow it to melt. Crack one egg onto the cheese, using a spatula to keep the yolk centered atop the tortilla. When egg whites begin to set, carefully flip both to cook the other side for 1 minute until whites are fully set. Flip back and transfer to a serving plate. Repeat with remaining tortillas, eggs, and cheese, adding oil as needed.

Top each tortilla and egg with salsa. Serve alongside the prepared black beans and garnish with avocado, cilantro, and additional cheese as desired.
