Cut tortillas in narrow strips with scissors and set aside to dry. Heat oil in casserole. Cook garlic clove in oil until burned black and remove. Brown tortilla strips in oil and add tomato puree, onion, parsley, chili powder, bay leaf, and 2 cups water. Simmer for about 15 minutes or until tortilla strips are soft and soup is almost dry. Sprinkle grated cheese on top. Andrew
