Add all of the curry ingredients, except the red lentils and kale, to the Instant Pot and stir until combined. Do not drain canned tomatoes.
Add the red lentils on top of the mixture and gently press them into the liquid (do not stir the lentils into the mixture as this can result in a burn notice).
Secure lid in the lock position and press the “Pressure Cook” button and set the cook time to 5 minutes on high pressure.
When the timer is up. Immediately do a “Quick Pressure Release” to avoid overcooking the curry. Carefully open the lid and stir the curry.
Stir in the chopped greens until thoroughly combined and secure the lid. Set the Instant Pot to the “Keep Warm” setting and allow the greens to wilt for about 5 minutes in the curry. Press “Cancel” to turn the heat off and release the steam again, if necessary, before removing the lid.
