"Create a gluten-free and dairy-free tortilla chip skillet soup recipe using ground beef, tortilla chips, onion, garlic, black beans, corn, tomato sauce, tomato paste, and spices (chili powder, cumin, paprika, salt, pepper). The soup should have a thick, skillet consistency, not runny. Include optional toppings like avocado or dairy-free sour cream alternative, fresh cilantro, and lime for garnish."
