Add water to the Instant Pot stainless-steel insert.
Place the steamer basket in the insert. Spread out the vegetables evenly in the steamer basket. Close the lid and set the vent to the sealing position.
Plug in the Instant Pot and set the Steam preset for 0 minutes at high pressure. If you prefer very soft vegetables, increase the cooking time to 1 minute
When the time is done, release the pressure manually by following your cooker's quick-release instructions. Open the lid after the pin drops.
Using heat-safe mitts, remove the steamer basket. Transfer the cooked vegetables to a bowl. Season with spices of choice, or drizzle with your favorite dressing. Enjoy!

Notes
Picking vegetables: Pick vegetables that share a common cooking time. Cruciferous vegetables, like broccoli and cauliflower, will cook in the same amount of time as carrots and green beans. Starchy vegetables, like potatoes and corn, will take longer.
Size of vegetables: Cut the vegetables to be about the same size to ensure even cooking.
Cooking time: 0-minute cooking yields soft vegetables with a slight bite. For a softer texture, increase the pressure cooking time to 1 minute.
Water Quantity: Adjust the quantity to the size of your cooker. 1 cup is enough for a 6-qt cooker. Increase it to 2 cups if using an 8-qt cooker.
Use a steamer basket: This prevents the vegetables from touching the bottom. If they sit in the water, they will boil rather than steam.
