Found this. I've never tried it, but it looks a) good and b) very easy.

Saag Bhajee

1 lb Spinach.
1 tblsp sunflower or groundnut oil
1 small onion, in long, thin slices
1 small clove garlic, finely chopped.
salt
knob of butter
1/2 tsp cumin seeds
1/3 tsp garam masala

Wash the spinach. Steam or boil until tender, in just the water that adheres to the leaves.
Heat oil over medium heat and fry the cumin seeds for 2 mins.
Add onion and garlic and fry until golden (gently, or the garlic will burn).
Add garam masala and stir well in. Fry for about 5 mins.
Add the drained spinach to the frying pan mixture, add the butter and fry gently for 5 mins. Season to taste.

If you try it, please let us know how it turns out.
