Daily Punch 2-6-20 Cook feat for DnD 5e

I think hit dice and temp HP don’t get enough love.  Let’s have a nice home cooked meal.

Cook

Nothing replaces a nice meal to help you start strong after a rest.  Gain the following benefits:

• Increase your Constitution by 1, to a maximum of 20.
• When you take a short or long rest, you can spend a ration or equivalent amount of food and cook.  You can’t do anything else during the rest, but you still count as resting for other purposes.  Any who eat of your prepared food can spend as many hit dice as they want instead gaining temporary hit points in addition to any hit dice spent to regain hit points as normal.  You can not spend more than half, rounded up, your hit dice to gain temporary hit points in this way.

Thoughts?
