Select the Sauté function and brown the 1.5 lbs Ground Beef with the diced 1 large Yellow Onion until fully cooked, then drain the excess grease.
Pour in a small amount of 1 cup Beef Broth and scrape the bottom of the pot to remove any browned bits.
Add the 30 ounces Dark Red Kidney Beans, 15 ounces Tomato Sauce, remaining broth, 2 tbsp Chili Powder, 1 tsp Ground Cumin, 1/2 tsp Celery Salt, 1/2 tsp Garlic Powder, and Salt and Black Pepper to taste into the pot, but do not stir the ingredients yet.
Place the 6 ounces Tomato Paste on the very top of the mixture to prevent it from causing a "burn" notice.
Secure the lid, set the valve to Sealing, and cook on high pressure for exactly fifteen minutes for deep flavor.
Allow the pressure to release naturally for ten minutes before manually venting the remaining steam and opening the lid.
Give the chili a vigorous stir to incorporate the tomato paste, then serve hot with Optional Toppings: Shredded sharp cheddar cheese.
