Put aboutfour tablespoons veg oil in pan. Heat on med. Put in black mustard seeds and chillis and heat until mustard seeds begin to pop. Then add spinich and a tiny bit of water, cover, and cook on low for a few minutes, until spinach is practically done.
Turn off heat, and add quite a bit of mint; stir it in well. Add a cap of Real Lemon (c), or fresh squeezed. Add two large dollups of yogurt-about 1/3 as much in volume as the spinach before cooking.
