Today's prompt is "an alien lands on your doorstep, what would you feed him?"
First things first; aliens are already here.
Next thing.... aliens have evolved to the point that generally they don't even have mouths. I would think they may be Breathatarians. There's no oxygen bars in the Keys that I know of, plus this is Vegan Month of Food, thus food is expected.
Food it shall be:
A little rum might help too......
Plant strong forever.
