This was an experiment and now I cook it for my family every couple of weeks and they love it. Mix and match ingredients to suit your own tastes.
I left out the bacon, vegetarian, and added a little flour to make the cheese sauce thicker as well as mustard powder into the sauce. Threw any veggies out of my garden, silver beet, broccoli etc, ended up with enough filling for two huge pies. Definite winner in our house. - 29 Aug 2017
