Sauté the chicken sausage, onion, bell pepper, and celery with the olive oil for 8-10 minutes until the sausage begins to slightly brown and the veggies have softened. Stir occasionally.
Add the minced garlic, tomato paste, and hot sauce. Cook for another 1-2 minutes before slowly adding the chicken broth to deglaze the pot. Add the remaining chicken broth, red beans (undrained), cajun seasoning, and bay leaves.
Seal and pressure cook for 25 minutes.
Vent, remove the bay leaves, and salt/pepper to taste before serving with your choice of rice*.
