Cut all the vegetables as mentioned or as per liking

Steam them in boiling hot water for 4-5 minutes starting from carrots to beans and to broccoli
Don’t over do. Vegetables shouldn’t leave the crunch.

Chop mushrooms and keep. No need to steam them. They get cooked when stir fried

Now strain vegetables in a colander and keep in ice cold water. This will help in maintaining the color.
