Clean and wash the Brussels sprouts, then toss in a deep bowl in the almond milk. Put the hazelnuts in a small bowl.
Heat the oil in the pan. Take the florets out of the milk one by one, turn them in the hazelnuts and add them to the pan. Crush or press the garlic clove and add to the florets. Fry everything for about 15 minutes. Season with sea salt and pepper.
