3.Meanwhile, make cheese and bacon toasts. Place bacon on foil-covered oven tray; grill until browned and crisp. Slice bread diagonally into 12 thin slices. Grill bread slices until browned lightly; spread with mustard, top with cheese. Grill until cheese melts; top with bacon.
4.Blend or process cauliflower mixture, in batches, until smooth; return to pan, stir gently over low heat until hot.
5.Divide soup among serving bowls; sprinkle with chives. Serve with cheese and bacon toasts.
The soup can be made two days ahead. The bacon toasts are best made close to serving.
