Horizontally slice the chicken breasts through the centre to make 4 even-sized breasts. Coat in 1/2 tsp salt, 1/2 tsp garlic powder & 1/4 tsp black pepper. Place to one side.
Fry bacon over low-medium heat until crisp, then remove bacon and leave the fat in the pan. Increase heat slightly to medium and add the chicken to the leftover fat, adding a drizzle more oil if you need to. Fry the chicken for a few mins each side, or until golden on the outside and white/piping hot through the centre. Place to one side and leave to completely cool. Slice into thin strips just before needed.
Add torn bread to a baking tray, drizzle with olive oil (1-2 tbsp) and sprinkle with a good pinch of salt. Give it all a toss then pop in the oven at 180C/350F for around 12mins, or until deep golden and crispy. Place to one side and leave to cool.
Add pasta to salted boiling water and cook to packet instruction. Drain and rinse with water until completely cool. Give it a very good shake in the colander to remove as much water as possible.
Whilst the pasta is cooking, add mayo, parmesan, anchovies, mustard, Worcestershire sauce, garlic, lemon juice, salt and pepper to a food processor and blitz until smooth and fully blended.
Add drained pasta to a large serving bowl. Top with chopped lettuce, bacon, chicken, croutons and shaved parmesan. Pour in all the dressing (or the amount of your preference) then give everything a good toss. Serve up and enjoy!
