This step helps bring out the flavor of the potatoes. Now, pour in the vegetable broth. Bring the mix to a gentle boil. Once boiling, reduce the heat to low. Cover the pot and let it simmer for about 20 minutes. The potatoes should become tender and easy to pierce with a fork. Once the potatoes are cooked, remove the pot from heat.
