Add chickpeas and water to the Instant Pot®. Lock lid.
Press the Beans button and cook for the default time of 30 minutes. When timer beeps, let pressure release naturally for 10 minutes. Quick-release any additional pressure until float valve drops and then unlock lid. Drain any extra liquid.
Stir in remaining ingredients. Switch to low pressure and simmer 4 minutes to heat through and wilt spinach.
Transfer mixture to a serving dish and serve warm.
