How to cook frozen veggies to retain their nutrients and flavor?

To cook frozen veggies while retaining their nutrients and flavor, it is best to steam them rather than boiling or microwaving. Steaming helps preserve the nutrients and flavor by cooking the veggies gently. Simply place the frozen veggies in a steamer basket over boiling water and cover with a lid. Steam for a few minutes until the veggies are tender but still crisp. Season with herbs, spices, or a drizzle of olive oil for added flavor.
