1. Preheat the oven to 210 degrees and bring 350 ml of water per person to a boil. Meanwhile, slice the onion. Remove the seeds and slice the red chili pepper.
2. Cut the pumpkin into quarters. Remove the seeds and cut it into small pieces. It is not necessary to peel it. Drain the chickpeas in a colander, then rinse them under the tap.
3. In a soup pot, heat the olive oil and sauté the onion and chili pepper for 1 minute over medium-high heat. Add the pumpkin, cumin, and half of the chickpeas, then sauté for 4 minutes.
4. Crumble the bouillon cube over the pot, add 350 ml of boiling water per person, and bring to a boil covered. Let simmer for 15 minutes.
5. Meanwhile, on a baking sheet lined with parchment paper, mix the remaining chickpeas with honey, then bake for 15 minutes.
6. Add the bread during the last 5 minutes. Finely chop the mint leaves.
7. Remove from heat, add the red wine vinegar, and blend using an immersion blender. Season with salt and pepper. Add a little boiling water if you want to thin the soup.
8. Serve the soup in bowls, then garnish with the roasted chickpeas, mint, sour cream, and olive oil. Serve with bread.
