Surely it's no big deal serving both dishes...........boiled cauli and cheesy cauli mash? I like to make cauliflower/brocolli cheese baked in the oven but our youngest doesn't like it and prefers it just boiled, therefore that's what he gets. Like all things in life we have to respect other people's choices/decisions in life and it's no different when it comes to food @ExD
I had fussy relatives visiting after Christmas too. I tend to cook a variety of dishes and put it all on the table for people to choose for themselves. - along with lots of vegetables and salads. It's a habit I got into when my niece and nephews were small.
