Serph here may have convinced some people to stock up on monster meat as an alternative/supplement to the Convoy breakfast, so if Kaidan isn't opposed to eating monster meat... :')

Also he knows Viktor is planning on trying to grow some of the farmland plants from the March event, so Serph would probably suggest to him to get in touch if he's interested in cooking. Serph himself will never go to the kitchen to eat though because he's uh. A demon cannibal. I have an opt out here.

But also monster meat isn't an issue, Serph can easily help hunt monsters for the kitchen; he actually hunts monsters every night in secret so it's not that much extra work for him.
