Once peppers and onions are diced, keep jalapeños separate from the other diced vegetables.
In a large (14-inch or more) skillet, sauté diced onions and peppers (not jalapeños) in 4 tbsps. olive oil.
Let diced veggies sit for 5 minutes on MEDIUM HIGH, then stir. Wait 5 more minutes, stir, then 5 more minutes.
After those 15 minutes, add diced jalapeños and stir them in with the rest of the peppers and onions. Sauté, stirring occasionally, for 15 minutes with the rest of the peppers and onions.
Once everything is nicely brown, remove peppers and onions from skillet into a bowl.
Add 1.5 pounds ground beef to the skillet. Wait 2-4 minutes before breaking up into chunky pieces. Once brown, pour into a colander or mesh strainer to strain fat. Add back to the skillet.
Add 2½ tbsps. chili pepper, 2 tbsps. smoked paprika, 1 tbsp. garlic powder, 1 tsp. salt, and ½ tsp. pepper. Add back onions and peppers, and mix thoroughly. Sauté for 1-2 minutes more.
Add beef, onions and peppers into the crock pot or Instant Pot. Pour in 16 oz. spicy salsa, 14.5 oz. diced tomatoes, 15.5 oz black beans, and (after draining) 15.5 oz. red kidney beans. Stir everything together, place the lid on top and slow cook on HIGH for 4 hours. Once done, give it a taste. If you want to add more heat, start with 1 tsp. of cayenne pepper and increase by half-teaspoons to increase the heat to taste, and serve.
