Wash and cut the vegetables into even pieces
Add 1 to 2 inches of water to a pot
Place a heatproof colander, sieve, or metal strainer inside the pot without letting it touch the water
Put the vegetables in the colander or strainer
Cover the pot with a tight-fitting lid
Bring the water to a boil, then reduce to a simmer
Steam until the vegetables are tender
Check the water level occasionally and add more if needed
Remove the vegetables carefully and serve immediately
Use a metal bowl set on a trivet or ring if a colander is not available
Use a microwave-safe bowl with a little water and a loose cover if steaming in the microwave
Use a foil ball or small heatproof rack to keep vegetables above the water if needed
