Add all ingredients to Instant Pot except for spinach and lemon juice, making sure you add lentils last. Cook on high pressure for 3 minutes. Instant Pot will take about 15 minutes to come to pressure. Do a quick release of steam then open lid when it's safe to do so.
Stir in spinach and lemon juice, then serve and enjoy!
