Turn your pot on to saute mode and when it says HOT, add the ground beef to the pot. Let the beef cook, stirring and breaking up as it does, until it's completely crumbled and browned all the way through. Strain off excess grease.
Add the onion and garlic to the meat mixture, and let it saute for another 2-3 minutes- just until the onions have softened.
To a medium mixing bowl add the stock, fish sauce, soy sauce, tomato paste, and cocoa powder. Whisk together until evenly combined. Pour into the pot, and using a sturdy wooden spoon scrape the bottom as need to deglaze. Turn off/cancel saute mode.
Add the tomatoes, beans, jalapeno, and seasonings to the pot and stir together to evenly combine.
Add the lid, turning to close, and set the vent valve to the sealed position. Pressure cook on HIGH pressure for 10 minutes.
Let the mixture sit when done until the pressure has naturally released, about 20 minutes. Carefully open the vent valve to release any remaining steam.
Open the lid carefully, and stir the hot chili.
Ladle into bowls, and serve with your favorite toppings.
