On the stove, using your pot, heat about 1/2 cup of water to a simmer. Fashioning a piece of aluminum foil into a bowl, place into it your broccoli (or whatever), and put your bowl of vegetables into the pot so that the edges of the bowl are away from the sides of the pot, and cover with a lid. Steam for however long your recipe says.
