Instructions

Heat 1 tablespoon oil in a large saucepan over medium heat. Add onion and ginger; cook, stirring, until starting to soften, about 3 minutes. Add cumin, turmeric and cayenne; cook, stirring, for 30 seconds. Add squash, coconut milk (reserve 4 tablespoons for garnish, if desired), broth, half the apple slices and salt. Bring to a boil. Reduce the heat to maintain a simmer and cook, stirring occasionally, until the squash is tender, about 20 minutes. Stir in lime juice. Remove from heat. Puree the soup in the pan using an immersion blender or in batches in a blender. (Use caution when blending hot liquids.) Divide ½ cup cheese between 2 slices of bread. Top with the remaining apple slices, cheese and bread. Heat the remaining 1 tablespoon oil in a large nonstick skillet over medium heat. Add the sandwiches and cook until lightly browned on both sides and the cheese is melted, about 2 minutes per side. Cut in half. Garnish the soup with the reserved coconut milk, more cayenne and ground pepper, if desired.
To make ahead: Refrigerate soup (Steps 1-2) for up to 3 days.
