Do snack food companies have curry, teriyaki, Korean, Mexican, thai, chinese, hamburger, hot dog, bbq, etc. oreos?
Depends on the snack food company. Some only specialize in a certain type of food, style, or flavor. Like Frito-Lay company sticks to relatively salty snacks, but they don't make beef jerky, Chinese food, or hamburgers or hot dogs etc. And Oreos is not made by Frito-Lay so they will not have Oreos.
Yes, all that and more.
What's a snack food company?
they probably have everything
