Brown bacon in a 12-in. frying pan. Drain on a paper towel, leaving 1 tbsp. bacon fat in pan. Cook beans and chiles in the pan over medium heat, stirring often, until simmering.
Make 4 wells in beans with a spoon and crack an egg into each. Cook, covered, just until eggs set, about 4 minutes. Top with cheese, green onions, tomato, cilantro, avocado, and reserved bacon. Serve with tortillas.
