Bring a large pot of salted water to a boil then turn heat down and keep at a simmer with a lid on top.
Heat 1 Tablespoon extra virgin olive oil in a very large (12"+) skillet over medium-high heat. Add turkey sausage and onions. Saute until sausages begin to brown, 2-3 minutes.
Add remaining Tablespoon extra virgin olive oil to the skillet then add zucchini and peppers. Season with salt and pepper. Saute until zucchini and peppers are just barely crisp tender, 3-4 minutes (don't overcook).
Meanwhile, turn heat under pot of water up to high. Once boiling, add gnocchi and cook according to package directions.
Add garlic and red chili pepper flakes to skillet with vegetables and saute until garlic is fragrant, 30 seconds. Add cherry tomatoes and basil then toss to combine.
Scoop cooked gnocchi into skillet then toss to combine. Add chicken broth and simmer for 1 minute or until broth is reduced and a thin sauce has formed.
Season, as needed, with more salt and pepper and serve in bowls.
