Sweet Potato Soup with Crispy Tortilla Topping

Heat oil in a large pot over medium heat. Add tortilla strips and cook, stirring occasionally, until golden brown and crispy, about 5 minutes. Transfer with a slotted spoon to a paper-towel-lined plate. Sprinkle with 1/4 tsp. salt.

Add poblano, onion, chili powder, and the remaining 1/2 teaspoon salt to the pot. Cook, stirring, until the vegetables are beginning to soften, about 2 minutes. Stir in broth, sweet potatoes, tomatoes (with their juice), and beans. Bring to a simmer. Cover and simmer, stirring occasionally, until the sweet potatoes have softened, about 20 minutes.

Stir lime juice into the soup. Ladle into 6 bowls and top each serving with radish slices, pepitas, queso fresco, avocado, and the tortilla strips.
