Heat oil in a large saucepan. Add tomatoes, garlic, hominy, leek and chili and roast over low heat for 2-3 min, or until vegetables are soft.
Blend half of the vegetable mixture together with the mashed avocados using a food processor or hand blender until creamy. Pour the mixture into a clean saucepan.
Add vegetable soup, milk and remaining vegetables and simmer on low heat for 3-4 min until soup is hot. Ladle into preheated individual soup bowls, garnish with leek shavings and bring to table on the spot.
Tip: When you bring the soup to the table cooled: Transfer soup from food processor to a large enough bowl, stir in clear soup and milk, cover and chill in refrigerator for at least 4 hours.
