Season the salmon fillet(s) with salt, pepper, and garlic powder.

Add the water and lemon juice to your Instant Pot, and place the steamer rack inside. Place the salmon on the rack and top with the lemon slices. 

Secure the lid and use the manual setting to cook on high for 3 minutes.  

Once the timer goes off, press cancel and turn the valve to release the pressure.

To cook the broccoli and kale, remove salmon from rack, and place vegetables on top of rack. Press sauté, and allow them cook in the lemon water broth in the pot for about 3 minutes or until tender. Cover the pot with the lid while cooking with the vent open, or use a certified Instant Pot lid instead.
