i got a rice and veggie steamer, but their were no instructions in the box?

you didnt mention the make of the steamer, if its electric or bamboo or a microwave one. so its difficult to provide you with proper instructions, you can go to a store that sells it and tell them your problem they can copy the instructions 4 u, or look up the make on google and get there toll free number and call them they will send u instructions.however here is a basic way to steam rice and veg

In a large pot, bring an inch or two of water to a boil over high heat.

If you're using a steaming rack or a bamboo steamer (works great!) make sure it's clean and have it ready.

When the water is boiling, trim and cut your vegetables. It's best to do this as close to cooking as possible so they won't dehydrate or oxidize.

Cut all the vegetables the same size so they'll cook evenly.

Place them in the steamer, on the steamer rack

Steam them only until they're done; most cut vegetables only need to steam for a minute or two. Thicker pieces might steam for two to three minutes. Potatoes take 15 to 30 minutes.
