Heat the olive oil in a small saucepan over medium heat.
Peel the garlic and shallots and chop them finely. Also chop the chili finely.
Fry the garlic, shallot, and chili separately until crispy in the oil. Drain on paper towels.
Place the goat cheese in a bowl and add the cooled, crispy garlic, chili, and shallot. Season with fleur de sel and mix everything well together.
Chop the pistachios and spring onions finely. Roll the goat cheese mixture in the finely chopped pistachios and spring onions and shape it into a nice roll by pressing firmly.
Drizzle the slices of sourdough bread with olive oil, season with pepper and salt, and bake them crispy for about 10 minutes in a preheated oven at 190°C.
Cut the bread into pieces and serve immediately with the goat cheese roll.
Tips
For an extra spicy taste, leave the seeds of the chili. Use a sharp knife to finely chop the shallot and garlic so that they become evenly crispy.
