Potatoes: If you don't have any leftover potatoes, start by cooking the potatoes. Let cool slightly, peel, cube, or thickly slice them. Set aside.
Chop: Finely chop the onion and the garlic cloves.
Cook ground beef: Heat the oil in a large skillet. Add the ground beef and stir for a few minutes until the meat changes color.
Add the onion and the garlic and cook until the onions are translucent and the ground beef lightly browned for about 5 minutes.
Chop vegetables: In the meantime, halve the zucchini lengthwise and slice the halves. Chop the bell pepper into cubes. Add both to the skillet and fry for 2-3 minutes.
Simmer: Add the broth, cover the pot and cook for about 5 minutes or until the veggies are done to your liking.
Add the potatoes and reheat them.
Add cream, crème Fraiche, chopped herbs, salt, and pepper to taste.
Stir carefully and serve immediately as suggested above.
