In a large non-stick skillet, heat oil over medium heat and caramelize onions with salt for 15 minutes, covered, stirring regularly.
Deglaze with balsamic vinegar and cook for a further 2 minutes. Set aside.
Hummus
While onions are cooking, place all hummus ingredients except garlic in a blender and pulse until very smooth. Add garlic and 1/3 cup (80 ml) reserved caramelized onions. Mix by hand.
Serve the hummus with the remaining caramelized onions.
