Preheat the oven to 180 °C.
Halve the pumpkin and remove the seeds. Score the pumpkin halves with a knife, brush with a little oil and place with the cut side up on a baking sheet.
Mix the chickpeas with oil, salt and paprika powder and place in a separate small baking dish or baking tin.
Place the pumpkin and chickpeas in the preheated oven. Take the chickpeas out of the oven after about 20-25 minutes and set aside.

Halve the cherry tomatoes.
After about 40 minutes, remove the pumpkin from the oven and use a fork to check if it is soft.
Put the guacamole on the two pumpkin halves, then add white beans and halved cherry tomatoes.
Put 2 tablespoons of creme fraiche on the cherry tomatoes and spread the crispy chickpeas and cranberries on top.
