Preheat the oven to 350°F.
Slice off the top of the pumpkin and scoop out the seeds and pulp. I like to save the seeds for roasting and discard the pulp.
Place the pumpkin and its lid on a microwave-safe plate, pour 1 tablespoon of water inside, then microwave for 12-15 minutes, until tender. Let the pumpkin cool slightly, then move to a baking dish.
In a medium pot, cook the diced smoked turkey and diced jalapeno in the olive oil over medium heat until the jalapeno is beginning to soften, about 4 minutes.
Stir in the green chiles, cayenne, and cumin and cook until fragrant, about 2 more minutes.
Sprinkle the flour into the pot, stirring to coat the turkey and peppers and cook until the flour is just toasted, about 2 minutes.
Pour in the chicken broth and wine. Bring to a simmer and stir until smooth.
With the mixture just barely simmering, whisk the cheeses into the broth, about ½ cup at a time, waiting for the cheese to melt before adding more.
When all the cheese has been incorporated and the dip is smooth, ladle the cheese dip into the pumpkin in the baking dish.
Bake the pumpkin with its lid on for 10 minutes.
Serve with tortilla chips. Be sure to scoop some pumpkin along with the cheese dip.
