1. Place tomatoes and jalapeños in a blender. Add broth, salt, and garlic. Cover and process on high speed for 1 minute or until smooth; set aside.
2. Heat a 12-inch sauté pan over medium-high heat. Add oil; swirl to coat. Add onion; sauté 2 minutes or until just tender, stirring occasionally. Add tomato mixture to pan. Bring to a simmer. Reduce heat to medium-low, and continue to simmer, uncovered, for 10 minutes, stirring occasionally.
3. Add chips to pan, and stir to coat with tomato mixture. Crack eggs, 1 at a time, over chips, evenly spacing them in a circle inside pan. Reduce heat to medium-low, cover, and cook for 5 to 7 minutes or until eggs are set but still runny in the centers. Remove pan from heat. Arrange avocado slices over eggs. Top with dollops of sour cream and a sprinkle of cilantro. Serve immediately.
