Veggies can be easily steamed even without a fancy food steamer.
On top of the stove: you will need a large pot and a steamer basket or collander that will fit inside. Fill the pot with water that barely reaches the bottom of the colander or steamer basket. Once the water comes to a boil, add vegetables and put a loose-fitting lid on top to cover. If your lid is more fitted over the colander, position it so that one side hangs over the colander just enough to let the steam escape.
In the microwave: Place vegetables in a microwave-safe bowl, add no more water than what it takes to rinse your vegetables before washing. No additional water is needed! Cover the bowl with microwave safe plastic wrap, leaving one corner open to vent.
