Grits = Cornmeal porridge (corn = maize)

Usually eaten in the southern US with butter and salt as a breakfast staple, though commonly eaten with fried fish at other mealtimes. People in other regions sometimes add milk and sugar instead of salt and butter, treating it much like oatmeal or Cream-0f-Wheat.

Grits are very bland and eating them by themselves is something most people would do only to stave off starvation. They're only good as a filler item served along with real food like eggs, bacon, or fried catfish.
