Heat canola oil in the pressure cooker pot over medium heat until it glistens.
Add sausage slices and brown for about 2 minutes per side. Remove and set aside.
Add ground beef or turkey to the pot and cook until no longer pink. Drain excess fat if needed.
Add in diced onion and celery. Cook for about 5 minutes, stirring frequently, until softened.
Return sausage to the pot, then add broth, carrots, potatoes, Italian seasoning, garlic powder, black pepper, tomato sauce, French onion soup, mushrooms, and bay leaf. Stir gently.
Lock the lid, set to sealing, and pressure cook on low for 10 minutes. Use slow release once finished.
Carefully open the lid, discard bay leaf, and serve hot.
