Add chorizo to Ninja Foodi and sauté until fully cooked. Chorizo should be crumbly and browned. Be sure to stir regularly so that the chorizo does not stick to the bottom of the pot. If your chorizo starts to stick to the bottom of the pot, use a plastic spatula to gently scrape it off.
Add Rotel tomatoes and chilis and stir until combined.
Add in Velveeta cheese. DO NOT STIR! If you stir after you have added the cheese, the cheese is likely to stick to the bottom of the pot and burn.
Close pressure cooking lid. Move valve to "seal" position. Pressure cook on high for 1 minute.
Once the timer beeps, move the valve to the "vent" position and quick release pressure. If liquid starts to come out of the valve, close the valve and let pressure naturally release for 3-5 minutes and then quick release remaining pressure.
Stir everything together until well combined.
Serve with your chips, tortillas or veggies. Enjoy!
