Melt butter in a saucepan. Add leek (cut in strips) and stir-fry.
Add green beans, peas, mushrooms, strips of red & green capsicum and pour over 400 ml of Vegeta Gourmet Liquid Stock. Simmer on low heat for 10 minutes, and add cauliflower and corn.
Add the remaining stock and cook for another 10 minutes.
Finally stir in corn flour (previously mixed with 50 ml of water) and cook for another 1-2 minutes.
Serve as a light meal, or as a side dish with your favorite steak.
You can replace the butter with olive oil, and chop the vegetables in to larger pieces to offer a different look, when serving.
