I use the carcass from roast chicken, put it in the slow cooker with lots of veggies, garlic and ginger. And let it slow cook away for 24 hours or so. The broth alone is a superstar. But if you want to make it more enticing for everyone, strain the stock, add more veggies and maybe chicken pieces or a packet of chicken noodle soup. Great immune booster

A teaspoon of olive leaf extract will build up the immune system. It’s a horrible taste but worth it.

Thanks for all that great suggestions … i hate the flu
