Seasoning makes every meal better when used correctly. Firstly, herbs and spices contain little to no calories. Secondly, you can season literally anything to improve its taste. Admittedly, you need a fundamental understanding to use seasonings appropriately.
My obsession with seasonings came from a time in my life when I tried a vegan lifestyle. You cannot understate how bland vegetables get day after day. While my love of meats won over in the end, the lessons I learned from trying so many seasoning mixes stuck with me.
