We’re in an obesity epidemic and most people don’t know how to cook even very basic meals.
Make space for it, squish other classes if you need. Make it mandatory, everyone has to take it. Maybe even ongoing through multiple grades.

Under financial literacy, it needs to be taught how tax brackets work. The amount of people that foolishly believe that taking a $2 raise will result in less take home pay is too damn high.
