Peel and dice the garlic and onion and sauté with a little oil in a pan. Add the minced meat and fry. Season to taste with vegetable broth.
In the meantime, wash, halve and core the peppers. Cut the feta cheese into cubes and wash the rocket.
As soon as the minced meat is seared, remove the pan from the stove. Add the diced feta cheese and rocket and mix well.
Pour the minced meat mixture into the peppers. If you like, you can sprinkle them with a little Parmesan cheese.
Bake the pepper halves in the preheated oven on the middle rack for 10 minutes at 180 ° C (200 ° C top / bottom heat). Alternatively, you can heat them in a pan with a lid on medium heat.
