What can I cook for a picky family?

Some weeks my family will come up with the weekly meals together and I will plan a one week menu out. I will go over the weekly meals with my family and see what food sides we can add or delete from the daily main meals so that everyone is happy. Planning out the meals for the week and posting them on the refrigerator really seems to help with the picky eating because we came up with the menu choices together as a family and everyone knows what to expect each day so there should be no complaints.
