The golu looks pretty much the same since last year.
Below are a few sundal recipies that you could use:
Paccha Payaru (Green Gram), Payatham Paruppu (Moong dal), Kadala Paruppu (Bengal Gram), Green Peas, White Channa Dal , Groundnut, Kaaramani (English?), Mocchakottai (Kidney beans), black channa dal. [Contact the mother-in-law for further details / help :-) ]
1.Soak any of the ingredients above for 2 hours.
2.Boil for a while. Drain the water.
3.And seasoning (mustard, curry leaves, green chilli) and the boiled dal/gram and saute with salt to taste.
4. Sprinkle Grated coconut and serve.
Also, if you are looking at a few simple gift ideas, you could buy a few Acrylic paints, a couple of brushes. Buy small clay diyas and paint them. It is not all that expensive, it is personalised and looks grand as well.
Here is a sample of the diyas I painted.
