When I was a young cook coming up the chef that I trained under would make us mix bins of this stuff and we used it in everything. It is a general purpose seasoning mix and so easy to make but at the same time so flavorful. There are plenty of versions of this which one can purchase but it is very simple to make. At home I use the reduced salt version (which is posted here) but at work I up the salt to equal proportions with the other seasonings. Anyhow, adapt it to your liking, keep a small bowl or container next to your stove and you will always have a simple but flavorful seasoning at hand.
