Seriously folk´s, insanely delicious! To make this dish I used a mix of dried parsley and fresh parsley, as well as dried thyme, fresh rosemary and some good-quality saffron threads. Make sure you don´t use imitation saffron here, as the saffron is what really adds a HUGE flavor to this dish.

TIPS & TRICKS to make this recipe: I used a brown onion, but you can you use any type of onion you like. I would just stay away from sweet onions. Make sure to cut your onion slices evenly, that way they all roast evenly. If white wine is not your thing, you can substitute it for white grape juice or veggie broth. Though the flavors won´t be the same, the dish will still be rocking good.
