In the bowl of a large food processor, add the herbs, garlic, spices, saffron threads, and a big pinch of kosher salt. Add the lemon juice and zest.
Run the food processor to combine, and while it is running, drizzle the olive oil from the top opener. Don't over-process it, it should have a little texture to it at the end.
Taste and adjust seasoning to your liking.
