Roast the hazelnuts in the oven at 180 ° Celsius for 5-10 minutes. If you want to, rub the skin with a tea towel, it works well, but it`s a relative mess. If you leave the skin on, you have it in the salad (and in your teeth) and it really doesn`t look nice.
Put the broccoli florets, feta and tomatoes in a bowl. Mix the dressing ingredients well and season with salt and pepper to your own taste (be careful: Feta is quite salty, I never use salt) and pour over the salad.
Add the cooled hazelnuts.
Tip:
Briefly blanch the broccoli, then it will be softer.
