I'm a US native speaker.

1) Macaroni and cheese. Nowadays the name is usually shortened to "Mac and cheese."

2) Chicken and rice. I think my mom wanted to avoid the ethnic stereotype of "chicken soup and rice." When I was a kid and I got sick, my mom always gave me chicken and rice. The chicken would have been broiled, or fried without any breading. The rice was always Uncle Ben's Converted Rice, and today, this is still the only rice that tastes "right" to me.

3) A peanut butter sandwich.

@Som YUM the Bengali sounds amazing!!

I have two.

The first is traditional Bengali: plain fragrant rice with plenty of ghee (clarified butter used widely here), with either mashed potatoes and boiled eggs flavoured with a few drops of raw mustard oil OR lentil soup (we call it daal) and crispy fried potato shavings (not chips but similar).

The other is plain white bread soaked in cold milk, with a fair bit of orange marmalade, honey, raisins and cashews. This is my own invention so it's not traditional at all.

@Dan Smith The chicken and rice sounds like “home” you probably think of your mom anytime you have it!

hahaha I know five guys I always thought it was a bit too greasy for me, but I can see why you keep going back!! @Alex Nguyen
