Prepare the Kamado BONO grill for indirect cooking, light the charcoal with a fire starter, and place the stainless steel grates.
Wait until the temperature reaches 180 degrees Celsius. Adjust the top and bottom air vents to maintain a consistent temperature.
Cut off the top of the pumpkin and scoop out the seeds. Leave the flesh intact.
Place a cast iron skillet on the grates, heat it up, and sauté whole vegetables until they are browned and soft.
Transfer the pumpkin to the skillet and cook for about 30 minutes.
During this time, blend the vegetables, add water and cream, mix in the cheese, season with spices, and pour the mixture into the roasted pumpkin. Cook for another 30 minutes.
