Preheat the oven to 350 degrees F. Slice corn tortillas into triangles, arrange on a baking sheet and cook 5 to 6 minutes, rotate, and cook another 5 to 6 minutes, or until lightly golden and crisp.
As the chips bake, bring chicken broth, three-quarters of the jar of salsa and water to a boil, stirring occasionally, for 2 minutes. Add half of the shredded cheese and stir, cooking an additional minute to let the sauce thicken a bit. (It will look a little gritty; that's okay.)
Reduce oven to 325 degrees F. Pour chips into the skillet. Top with salsa mixture, saturating chips entirely. Top with remaining cheese and bake for 8 to 9 minutes, or until the chips have absorbed the sauce and the cheese is melted and bubbly. Remove from heat and turn off oven.
As the skillet bakes, fry bacon until crispy. Set on a paper towel-lined plate to cool. Use the remaining bacon grease to fry eggs, two at a time, until the whites are set but the yolks are still runny.
Sprinkle the bacon on the cooked chip mixture. Add eggs, then garnish with remaining salsa and cilantro. Top with avocado slices, if desired, and serve.
