Parboil the baby potatoes in salted water for 7 minutes. Rinse under cold water and drain well.
In the meantime, peel and cube the parsnips.
Place the boiled potatoes, cubed parsnips and whole tomatoes in an oven tray. Sprinkle some olive oil, nutmeg, turmeric and salt over the root veg. Sprinkle some olive oil and salt over the tomatoes. Roast for 15min at 180 degrees until tender.
While the root veggies are roasting, prepare the chard. Clean the chard leaves under running water. Slice the chard stems and leaves crosswise into pieces of your desired size. Boil in salted water for 5 minutes.
Drain well the cooked chard. Toss the chard in a pan with some olive oil and soy sauce and cook for 5 minutes until the flavours are well mixed.
Pan roast the halloumi. Reserve.
For the tomato sauce, peel the skin off the tomatoes. In a blender, blend the garlic cloves, spices, tomatoes, tomato passata, vinegar and bread until you get a smooth sauce. Season to taste.
To serve, in a large serving plate place first the root veg, then scatter the chard and halloumi. Toss in the tomato sauce (make sure is heated).
