Olan 1- Kerala receipe

When my patti taught me this receipe, I was wondering how can a receipe tastes good without any masala or any garnishing. But this one tastes really good and its very easy to make. The main ingredients are as follows..
Ingredients:-

1. Winter melon - 1/4 (chop it in an inch size)
2. Pumpkin - 1/2 (chop it in an inch size)
3. Coconut oil - 1 1/2 tbsp
4. Salt to taste
5. Green chillies - 1 or 2 (according to taste)

Take a pan, cook the winter melon and pumpkin adding salt and green chillies to it. Try to avoid, lot of water cos, both the vegetables are watery veggies. Do not over cook or mash the veggies. When it is done, turn off the stove and add the coconut oil to it. Thats it. This is a traditional dish in kerala.
