Chilled Yellow Pepper and Garlic Soup

With the temperature soaring to beyond 100 degrees , with no dip in the numbers coming for atleast a week,and even then the weatherman has the nerve to charactarize, 95, as "a cool down". It is "an inconvenient truth", here in Dallas ,that it is HOT!
I love cold soup. Fact is, given the choice, I prefer cold saki, and cold coffee to the more popular serving choice of hot, but give me soup in any of its incarnations.
