Heat 1 tablespoon of oil in a large skillet over medium-high heat. Once the oil is hot, add sliced sausage. Sauté, flipping sausage frequently, for 1 to 2 minutes or until sausage slices have some browning. Remove from pan and set aside.
Reduce heat to medium. Add remaining 1½ tablespoons of oil to skillet with the zucchini, onion, and bell pepper. Sprinkle with salt, oregano, basil, garlic powder, onion powder, and pepper. Stir. Let cook until the onion is translucent and peppers and zucchini are close to tender, about 5 to 10 minutes.
Add sausage back to the skillet along with minced garlic. Stir. Cover so everything heats through for 1 to 2 minutes. Taste. Add extra salt if desired. Garnish with chopped fresh basil (optional).
