If your food storage is full you can take the following steps to create more space:
1. Check the menu board to see if there are any orders you can fill.
2. Cook extra dishes… try to concentrate on those that require 2 or 3 ingredients from your club storage.
3. Use the crop exchange area to place surplus crops.
4. Donate items to your team members using the donation tool in the in-game chat tab
5. Delete orders from the menu board until you are given one you can fill.
