In the meantime, dice the onion and leave it in margarine. Cut the tomatoes into medium-sized pieces and add them. Cut the beef ends into slices and add them as well. Simmer gently for about 7 minutes over medium heat. Deglaze with the white wine, crumble the stock cube and stir in. Season with thyme and pressed garlic.
Cut the bell pepper into pieces, fold in and bring to the boil.
Cut the potatoes into larger cubes and place in the pan, then turn off the oven and leave the pan with the lid on the hot plate for 10 minutes. This way the peppers stay firm to the bite.
Tip:
If you like, you can then bake the pan of vegetables in the microwave or oven with cheese.
