Peeling and grinding take too much time. Make a paste of onion, garlic-ginger, tomato puree and store it in a refrigerator.

If you are making pulses, add a teaspoon of salt. It helps to cook the pulses easily and gives a great taste.

Wash the vegetables. Make it dry and cut down it. Store in a zip lock bag in a refrigerator and take out the next morning for easy making. 

Hope these tips will help to speed up cooking.
