1. If using uncooked chicken fillets cook as you prefer until nice and white. Please make sure the meat is cooked all the way through.
2. Slice chicken fillets into bite size pieces, cover and lay to one side (if using precooked and sliced chicken pieces as I sometimes do, simply leave to one side until needed!).
3. Grill/broil lean bacon.
4. As bacon is cooking, put the penne into a sauce pan, add boiling water and boil until pasta is as soft or as firm as you prefer (*Optional - add a pinch of salt if you prefer, I never do though).
5. Slice the spring onion up into small pieces.
6. When the bacon is cooked, slice the bacon up into small-ish pieces.
7. When pasta is cooked, drain and empty into a mixing bowl.
8. Chop the lettuce and line in a pasta bowl or plate.
9. Slice and dice the tomato.
10. Add the bacon, chicken, mayo, tomato and spring onion to the pasta.
11. With a little elbow grease, mix the primaries together. When everything is sufficiently mixed, spoon out and place on top of the lettuce.
12. Bon Appetit!
