Add ground sausage to enameled dutch oven and cook on medium high heat until crumbled and cooked through.
Remove sausage from pan, do not drain fat.
Add stew meat to pan and cook until browned on all sides.
When meat has been browned, remove from pan and set aside with sausage.
Stir in onions and let soften and lightly brown, about 6 minutes, stirring occasionally to prevent burning or sticking.
Stir in garlic, carrots, celery, and peppers.
Cook until vegetables are soft, another 7 minutes.
Stir in diced tomatoes, broth, beef, sausage, and seasonings and turn heat to high.
Bring chili to a boil, and then reduce heat to low and simmer for 15-20 minutes, until chili has thickened up slightly and reduced.
If using an Instant Pot, turn the Instant Pot to the Chili/Beans setting and place the lid on the pot - cook for 18 minutes and release naturally or manually.
Serve immediately and enjoy!
