Season the chicken with paprika, Italian seasoning, garlic powder, salt, and pepper.
Heat the olive oil in a large skillet over medium-high heat.
Cook the chicken for 6 to 8 minutes until golden brown and cooked through. Transfer to a plate.
In the same skillet, melt the butter.
Add the garlic and cook for about 30 seconds until fragrant.
Stir in the zucchini and cook for 3 to 4 minutes until slightly tender.
Add the corn and cook for another 2 to 3 minutes.
Pour in the chicken broth and lemon juice.
Return the cooked chicken to the skillet and toss everything together.
Cook for 2 more minutes so the flavors combine.
Stir in the parsley and garnish with Parmesan if desired before serving.
