Chicken and waffles is amazing, you should try it sometime.

Chicken for breakfast?

They were made of different stuff back then.

Your meal choices adapt when you have to wear a diaper for hours on end, and when you change that diaper its going to be in the equivalent of a large closet of confined space with two other guys. What astronauts choose is usually "low residue" meals. Meaning that your body absorbs nearly everything you eat. This would be the opposite of "high fiber" where there is a large amount of indigestible matter that passes all the way through. This was one of the reasons steak and eggs was so popular for launch day Astronauts. Its very low residue.

Chicken and waffles is a thing. Maybe he didn’t want to smell like syrup for a week so he skipped the waffles.
