Combine all of the chopped vegetables in a salad bowl.
Make a dressing from lemon, balsamic vinegar, olive oil and vegetable stock and season with sugar, salt and pepper. Pour the dressing over the salad and mix.
Arrange on plates and top with pine nuts and sheep cheese. Finally, you can grind a little pepper over it.
Variation: The salad also tastes good with freshly grated Parmesan instead of sheep`s cheese.
