I forgot - add your favourite spice mix to the fried veges .. the usual mix of salt, red chilli, turmeric, fenugreek seeds, garlic, ginger, cumin, coriander, cinnamon, black pepper, citric acid, methi leaves, carom, cloves..
I use the Shan Vegetable Masala .. about 2-3 teaspoons and then also add hot red chilli powder as I prefer it.
