Turn your Ninja Foodi on 'high saute'. Once heated, add the olive oil and ground beef. Saute for about 3-5 minutes, or until the ground beef is brown and cooked through.
Turn off heat, and drain any excess grease, if needed. Be careful, as the pot will be hot!
Add in the onion, bell pepper, jalapeno pepper, garlic, beef stock, crushed tomatoes, chili powder, ground cumin, paprika, ground black pepper, and salt. Do not stir.
Place the pressure cooking lid on the Foodi, secure and lock it, and turn the nozzle to 'seal'. Set Foodi to 'high pressure' for 5 minutes. Manually release the steam once cook time is up by turning the nozzle to 'vent'. Be careful when venting steam and use an oven mitt to avoid burning yourself on the hot steam!
Add in the kidney and pinto beans, stir well, and serve!
