Is this an unpopular opinion? Life skills classes are a great idea, my current high schooler took Culinary (geared more towards commercial kitchens but still cooking) and is taking financial literacy this year.
If physical education is mandatory, I agree that nutrition & cooking class, as well as budgeting/financial class, are part of a comprehensive education. I think they should bring back sex ed too.
Being able to cook well is more a function of experience, all my kids can cook now, because they like to eat and it's the easiest and most affordable way to get good meals. But the one who took the class does show more interest at a younger age.
