To make dressing, whisk mustard, oil and vinegar in a bowl, then season with salt and pepper. Flatten garlic with the side of a knife, discard skin and add to bowl. Leave dressing to infuse and discard garlic just before using.
Wash potatoes, place in a saucepan, cover with water and bring to the boil over medium heat. Cook for 20 minutes or until tender. Add eggs to cooking water in the final 7 minutes and cook until yolks are still slightly soft. Drain potatoes and eggs, and cool slightly. Cut potatoes into 1.5cm pieces and toss with 2 tablespoons dressing. Peel and chop eggs.
Meanwhile, strip away chicken breast meat in large pieces (reserve legs for another use), discarding skin and bones, then cut into 1.5cm pieces.
Halve avocados, remove stones, then cut into 1.5cm pieces. Place in a bowl and squeeze over juice from lemon. Finely snip chives with scissors over bowl, season and toss gently to combine. Cut tomatoes and blue cheese into 1.5cm pieces.
Heat a large frying pan over medium heat. Add bacon and cook, turning occasionally, for 3 minutes or until crisp. Drain on paper towel, then cut into 1.5cm pieces.
Starting with lettuce leaves, place salad ingredients in rows along a platter. Drizzle with remaining dressing to serve.
