Heat the chicken broth until boiling. Add the garlic and the chopped zucchini. Cover and simmer on low 2 to 3 minutes, or until the zucchini is soft and has cooked through. Pour the mixture into a blender (Note: you may need to blend the soup in 2 batches). Add the tahini paste, lemon juice, salt and white pepper. Puree until all ingredients are smooth. Pour the mixture into a large serving bowl, then chill thoroughly. Before serving, correct the seasonings; you may need more tahini, lemon juice or salt to punch up the flavors. Stir into each soup bowl (or into the main serving bowl of soup) a generous dollop or 2 of yogurt per person. Serve topped with the chopped red onions, passing more yogurt at table.
