In our family, this is called kadamba curry - kadambam being a flower string made up of different flowers. It's my most favorite and doesn't require boiling any vegetables. The only time consuming activity to make this is chopping vegetables. I timed it, and it literally got perfect al dente texture in exactly 4 minutes! This dish also travels well, and is great for picnics.
The best vegetables for this curry are potatoes, carrots, and peas. I like cauliflower, but if you don't like the smell of it, you can totally omit it. The key is to choose vegetables that have about the same cooking time, making sure none of them have an overpowering smell.
