Melt the margarine in a small pot and sauté the vegetables briefly. Pour in the stock and stew at low heat for about 3 minutes (the liquid should have almost evaporated). Season vegetables with salt, pepper and nutmeg.
Meanwhile cook the spaetzle in salted water according to the instructions on the packet. Drain the spaetzle and fold into the vegetables. Arrange vegetable noodles and dust with some paprika powder.
