Depending on your situation, location, and inventory you may end up with any type of food, drink, or heal-up in your bags.
Macros "fall-through" failed lines to the next, stopping when it hits something that works. Thusly, you can do something like this:
Code:
/use Conjured Croissant
/use Bladespire Bagel
/use Telari Grapes
/use Mag'har Mild Cheese
The above would use conjured food first or, if none, one of the various max-level foods that might be available.
