Preheat pressure cooker pot and add the Olive Oil (1 tablespoon).
Sauté the Onion (1), Bell Pepper (1), and Celery (2 stalk).
Add Garlic (2 clove) and Cajun Seasoning (1 tablespoon) and stir for 30 seconds or long enough to “bloom” the spices. Add Andouille Chicken Sausage (12 ounce), Chicken Broth (3 cup), Dry Red Beans (8 ounce) and Salt (to taste), and then seal cooker.
Bring to pressure and cook 15 minutes. Or if using an electric pressure cooker, cook 20 minutes.
Allow pressure to drop on its own at least 10 minutes.
Release remaining pressure, carefully open lid, and serve in bowls over 1/2 cup Brown Rice (2 cup). Enjoy!
