Preheat oven to 400 degrees. Slice the squash in half lengthwise and remove seeds and strings. Place, cut side down, on a greased baking sheet. Bake for 60-90 minutes or until flesh is fork tender. Cool then scoop out flesh.
For the Soup
Puree squash in a blender with the jalepeno, seasonings, and broth (in batches depending on the size of your blender). Transfer to a large stock-pot and stir in water. Bring to a simmer and cook for 10 minutes. Add more water or broth to reach desired consistency. Adjust seasoning to taste (adding more cumin or salt).
Serve with Pumpkin Seed Pesto.
Notes
regular basil pesto may also be used instead of the pumpkin seed pesto.
