This one probably belongs somewhere other than General Questions. Let’s try MPSIMS.

Every freaking day. That’s what we got at summer camp at the YMCA once. They never counted on a seminar for latin americans happening next door and enrolling their kids in summer camp at their all white neighbourhood. We revolted. In both senses of the word. Our reward:
fried chicken and watermelon. I am not making this up.
Wonderbread and miracle whip sandwiches with the crust cut off.
I always associated watermelon, really any melon, as “whitey” food, but that comes from my specific upbringing. I grew up in a small town of all white people. The local black people lived in the next town over which was a racially mixed town, black, white, and american indians, it was also where the Wal-Mart was which is where we shopped so I was aware of other races, but for the most part of my young life (until 10) I was only around white people. Every year we had a watermelon festival and all the country folk came together for this weekend festival and melons of all kind were everywhere. Melon artwork, melon cook-offs and melon racing are some things I remember from the fair. One year my brother even won the melon race and his prize…a big fat watermelon.
You mean “soda” of course. 
On the OP - it’s so regional, it really depends on where you ask the question. And I don’t have a good answer for my region; I don’t think I know any “typical” people, hehe.
You’d also have to specify which white stereotype you mean.
There three basic ones I guess:
The white bread suburban protestant and his food has been mentioned, so has the rich white upper crust fat cats. The third is the redneck, and they eat beef jerky and pork rinds and drink lite beer.
This is probably the only time in my life where I have ever heard about white people winning the watermelon stereotype. In fact, just a picture containing a single black person and a watermelon is enough to induce protests and indignation in some areas. Don’t get me wrong, I love watermelon but I think you are oblivious to a very common stereotype and public image (watermelons came from Africa with slaves BTW.)
That stuff seems pretty “white American” food. If you consider most of Europe to be “white people” I would say potatoes and bread.
One time I wrote a humor piece about the Pope for an ezine, and someone wrote me a nasty letter saying that I must lead a very “oatmeal” life (because I’m a Protestant?) So I’ll vote for oatmeal, too 
I don’t remember seeing fried rice while in China; lots of white rice and sticky rice but no fried rice; no kung pao chicken, either. Those are “white” foods, at least in the USA although I suppose some other ethnic folks eat them.
I THINK chimichangas are an American perversion of real Mexican food, although I’m not certain. I don’t think anything from Taco Bell can really be called Mexican food.
Back home in Texas, watermelons were universally considered to be black food; “Ni**** Ice Cream” was often used to describe watermelon. Strange how many white folks couldn’t get enough watermelon, though. Incidentally, Joe Louis, the great black boxer wouldn’t eat fried chicken or watermelon in public due to the stereotyping of those things as black food. And, he loved both of them.
I’m white and I’ll eat pretty near anything that’s dead, provided it hasn’t been dead all that long.
Hamburger Helper
Ooooh! I know! The Cracker!
I’m a southerner, and all our best food could hardly be called “white food.”
I’m pretty sure tuna casserole, green bean casserole and the aforementioned jello salad stuff.
As Cousin Eddie said in National Lampoon’s Vacation: “I don’t know why they call this stuff Hamburger Helper, it does just fine by itself”.
My vote goes to bologna on white bread. With mayo.
Lemonade?
I don’t know what races prefer Buffalo wings, but I think of them as the industrial north equivalent of “soul food”, i.e. finding a use for previously unused parts of an animal.
Right, southern poor whites and blacks ate the same foods, and rich whites ate food created by blacks. So I can’t think of a single food that’s “white southern”, if it’s southern food it’s neither white or black. So you’ve got to go north to get stereotypical white food.
I had a friend in high school that thought it was funny that white people drank so much milk. He was convinced because of this white people farted a lot more than black people. I haven’t heard this from any other black person I have met (it’s not the kind of thing that comes up however) so I’m not sure it’s a wide spread stereotype or not.
What about cottage cheese and canned tuna.
I would describe white people food as “meat and potatoes”.
