Wash spinach leaves and place them in a saucepan with 1/2 cup on medium heat for 5 minutes. After 5 minutes remove spinach from the saucepan and wash under cold running water. This process is called blanching. Leave spinach in a colander to drain out completely.
Now put all green veggies (peas, chopped beans, chopped green capsicum) in a microwave-safe glass bowl with 1 cup of water and microwave them for 10 minutes (covered).
