What will make us come together?

[UltraBudgie]

Off the top of my head

an anorexic
a bulimic 
a person going through radiation/chemotherapy
pork-centric meals for certain religions
Most aggressively hungover people
A person who stopped and picked up dinner on the way home
A picky eater isn't gonna be happy with any meal except thier favorite(s)

Or a child given quiche.

But there is something to be said for the surfacy "California multiculturalism" of food, music, and apparel. It's basic, yes, but finding something to appreciate in each other is a first step. The path to common ground begins with admitting that, in fact, there may actually be common ground.

The act of making the meal itself, this kindness can make them smile. Its not always about the food.

Can you please explain/expand what you say here as I must be missing something?

How can food unite us all?

Cook for anyone and see

The husband, who's wife never learned to cook.

Cooking is a fantastic couples event. My advice to them would be to adventure it together
