In a pressure cooker, sauté the chopped onions and brown the veal cubes in the heated olive oil.  Add 250ml water and cook for approximately 15 minutes, depending on the size of the meat cubes.

Empty the contents of the pressure cooker into an ovenproof dish, preferrably a lidded one. Add the stock cubes, tomatoes, sugar, garlic, salt and pepper, and the orzo.  You can use more or less orzo, depending on the size of your dish.  Add the wine and at least 250ml water.

Cover.  If your dish does not have a lid, cover well with alluminium foil.

Bake in a preheated oven, at 170 degrees C, for 1 to 2 hours.  After 1,5 hours, remove the lid, add the crumbled feta cheese, stirring it through the meal.  Sprinkle the grated Parmesan cheese on top, and return to the oven, uncovered,  for a further 10 minutes.

Keep an eye on it, until it is ready.
