On the west coast, the longer Delta regional flights serve LUVO brand meals. The choices are breakfast wrap or yogart in the morning, and wrap or salad in the afternoon and evenings. All are intended to be served cold, but I'm sure the FA will heat the wrap up as if it's a burrito if there happens to be an oven on-board. The flights are CRJ-900, 700 or EMB 170/175's operated by Skywest or Compass.
