Preheat oven to 400°F. Stir together beef, crushed chips, eggs, cheese, cilantro, and cumin. Shape mixture into 2-inch meatballs and place on a lightly greased wire rack over a rimmed baking sheet. Bake 20 minutes.
Meanwhile, cook onion and garlic in hot oil in a large Dutch oven over medium heat until vegetables are tender. Add tomato paste; cook, stirring, 2 minutes. Add tomato sauce, enchilada sauce, broth, and ancho chile pepper; bring to a boil, reduce heat, and simmer 10 minutes. Add meatballs, and simmer 15 to 20 minutes or until thoroughly heated.
