Preheat oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer). For the hummus, drain the chickpeas. Peel and chop the garlic. Finely puree the chickpeas, garlic, tahini and 75 ml water in a tall mixing bowl.
Season to taste with salt and lemon juice. Stir in 2 tablespoons of oil.
Onions peel and cut into slices. Wrap the tortillas in foil and warm them up in a hot oven for 10-15 minutes. Heat 3 tablespoons of oil in a frying pan and fry the onions for about 4 minutes.
Sprinkle with sugar and caramelise while stirring. Deglaze with vinegar, bring to the boil and simmer for 3-4 minutes. Season to taste with salt and pepper.
Drain the roasted peppers and artichokes. Chop the peppers finely, halve or quarter the artichokes. Wash parsley, shake dry and chop coarsely.
Take out tortillas and spread hummus evenly over them, leaving 2-3 cm of edge free. Spread caramelized onions, peppers and artichokes on top. Sprinkle with parsley and roll up into wraps.
