Native English speakers, do you say "and you?" instead of "how about you?"

Mostly "What about you?".

Interesting! Oftentimes I’ll even just use “You?” but usually only if my response to their question was fairly brief. “Did you go out this weekend? “Nah, I stayed home to catch up on Severence. You?”

I hear and use all of them

In my mother tongue, there is indeed such an expression, which is quite common. It might have been simplified to the extent that it can't be simplified any further, something similar to "you?"

Either "What about you", "How about you", or just "You". I'd say *how* is the most common one I use, but I don't use 'and you' in the *standard* situations it is used in in Romance languages. There are situations where I would use 'and you' - for example, if everyone were listing off something (such as their favourite pizza flavours) and the last guy didn't realise it was their turn - but those are quite specific and not very broad.

> "How are you" > "Not bad, and you" This would be almost daily. 

Sometimes. "How's things?" "Good, and you?"

Yes, it's used it English but not as frequently as in SP and PT. In everyday English we would generally reply to "How are you" with "Good, you?" rather than "Bien, y tú" that is the norm in SP even when speaking in the familiar.

Yes. “Not too bad, and you?” and other variants of this

I use phrases ranging from 'you?' to 'and how about yourself?' Can't think of the logic behind which phrase I use (and when) other than how talkative I feel at the time.

Yes, I say and hear “and you?” all the time. That said, it’s usually only said to professional acquaintances. It’s not something my friend group said to each other back when we were in high school, although we all say it to people out in the work force and with other acquaintances.

I think it kind of depends on whether I actually want to know, or am just using a greeting. My dear friend whom I haven’t seen since last summer: "Sparky! So good to see you! How’ve you been?" "Oh, I’ve been well! We all had the flu after Christmas, but we’ve all been fine since. And tell me how you’re doing!" Some random stranger: "How'ya doin?" "Fine. You?"

I say “and you” all the time

"How about you?", "What about you?", "And you?", "You?" or even "Yourself?" are all used in various degrees. It's really a personal preference in the end.

I absolutely use "and you?"

In an exchange such as this (a back and forth greeting), it can be very informal. There are lots of variations that all work: You? And you? How about you? What about you? How about yourself? How you doin'? (This one is more of a joke, I don't recommend unless you're friends with a person. It's kind of a fake flirty phrase)

I do but honestly it could be because I took five years of Spanish lol If the question is "how are you" my preferred response is "I'm good, I hope you are." Purely because in my experience it tends to end the small talk faster 💀

Mostly the and you would be used like part of the sentence answering the initial question. What about you would start another sentence.

‘and you’ feels very formal honestly. i’m sure there are situations where i wouldn’t bat an eye at it, but it sounds odd. ‘what/how about you’ and just plain ‘you?’ are most common where i am (edit: spelling mistake)

"And yourself?" I hear more often in reply to me asking them about their well-being.

“You?” or “And you?”

"jes fine, how boucherself?"

I say things that mean that, but not that phrase.

I never say "and you."

I used a mixture of "What/How about you/yourself?"

I have never used it in English. It seems really common in other languages and every time I start trying to learn one it's a phrase in thr first few lessons. "I like to eat sushi. And you?" Or something like that. But any time I could have used that phrase I have always used "what about you?" Or just "you?" Or I omit the proper context to you use instead of "i like sushi. What about you?" I just ask "do you like sushi?" I'm actually really curious if this is as common in other languages as it the courses make it out to be.

I do, though I would say mostly in formal settings. In informal settings, simply "you?", or something more specific to the person.
