I made Tomato pumpkin chutney as one of the side dishes for the mini tiffin, as I did not click a pic separately am using a collage pic which shows this chutney as one of the side dishes. The one next to the coconut  chutney.

Ingredients:

1 cup chopped tomatoes
1 cup chopped onions
1 cup chopped pumpkin pieces after peeling.
A tiny bit of tamrind ( can skip if using more tomatoes)
4-5 red chillies or as per your taste, pinch of turmeric powder
salt
some curry leaves
some finely chopped coriander leaves
2 tbsp sesame oil

To temper

1/2 tsp mustard seeds 
1-2 dry red chillies
1 tsp sesame oil 

Method

In a pan add the oil, let it heat up, add the red chillies , add the chopped onions, sautee well,

Furthermore add tomato and pumpkin pieces.
Add the small tamrind bit, curry leaves, turmeric powder and sprinkle little water. Cover and cook without mashing the mixture till it is almost dry but not too dry, towards the end , add the chopped coriander leaves .

Remove, let it cool, then blend to a smooth chutney.
Remove into a bowl and add the tempering.
Garnish with more curry leaves if you like.
Note..you can add garlic if you like ( I have not used it )
This chutney can be made for several tiffin items and also tastes great with curd rice
