Prepare Kale Basil Pesto according to instructions below.
Cook the gnocchi in a large stockpot of salted boiling water according to package instructions. Drain and set aside.
While the gnocchi is cooking, cook the chicken sausage in a saute pan according to package instructions. Once it has finished cooking, transfer the sausage to a separate plate and slice it on the diagonal into bite-sized pieces.
In the same saute pan, heat olive oil over medium-high heat. Add Brussels sprouts and saute for 5-6 minutes, stirring and flipping occasionally, until it is cooked through and begins to brown. Remove from heat.
Combine gnocchi, Brussels sprouts and Kale Basil Pesto in the stock pot, and toss until combined. Serve warm, garnished with extra Parmesan cheese if desired.
To Make The Kale Basil Pesto:
