Pumpkin Soup with Grilled Cheese Croutons

Sugar Pie pumpkins, sometimes known as sugar pumpkins or pie pumpkins, are smaller, sweeter and more flavorful than field pumpkins, which are the ones sold for making jack-o’-lanterns. Roasting them in the oven brings out their wonderfully earthy, nutty flavor, so it’s worth seeking them out, although you can substitute 4 cups (1 lb. 14 oz./940 g) of canned pumpkin puree if you’re in a hurry.
