More than 400 people have submitted questions for Curious Minnesota, the community-driven project that puts reader inquiries at the center of our newsroom's reporting.

Last week's winning question came from a reader who asked: Why are hot sandwiches served with mashed potatoes and gravy called commercials in Minnesota? Are they called that anywhere else? We'll be answering that question in the coming weeks.

Which of these questions should we answer next?
