Press the SAUTE button on the Instant Pot and let it heat up.
Add in the ground sausage and onion, cook until the meat is no longer pink. Add in garlic and saute for 30 more seconds.
Drain meat if desired.
Pour in 1/2 cup of the beef broth and "deglaze" the bottom of the Instant Pot with a wooden spatula to prevent the "burn" notice from happening.
Add in remaining beef broth, zucchini, green pepper, tomatoes, tomato paste, tomato condensed soup, sugar, basil, Italian seasoning, salt, and pepper.
Place the lid on the top of the Instant Pot. Move the valve to SEALING (not venting).
Press the PRESSURE COOK button and set timer for 5 minutes.
When the timer is finished, move the valve to VENTING and do a QUICK RELEASE with the pressure.
Remove lid, press SAUTE button and mix the frozen ravioli with other ingredients in the Instant Pot. Cook for about 3-5 minutes or until the ravioli is cooked (they will start to float to the top). Serve topped with shredded Parmesan cheese and fresh basil.
