Place all the herbs into a mortar and pestle and grind them down to make the mix a bit finer. You can also put them into an electric spice grinder and turn it all into a power for sprinkling.
I have to say I use the mortar and pestle method. I like it when you can see all the herbs. The only problem can be the rosemary it can be woody and long with sharp ends so I start by breaking up that first then simply add the rest and mash it until it's as I like it.
If you like you can also leave out the salt and season things with salt and pepper separately.
