Begin by heating 2 tablespoons of olive oil in a large skillet over medium-high heat. Allow the oil to shimmer for about 1 minute, signaling it's ready. Once hot, add the sliced cooked sausage and sauté for 5 minutes until the sausage is lightly browned. Remove the sausage and set it aside.

In the same skillet, retain 1-2 tablespoons of the oil used for the sausage; discard any excess. Add the chopped yellow onion and red bell pepper, cooking for around 4 minutes until they soften and become fragrant. Add the minced garlic, stirring for an additional 30 seconds until aromatic, then transfer the veggies to the plate with the sausage.

Using the same skillet, toss in the chopped zucchini and sauté for about 5 minutes until it softens and develops a golden color at the edges. Stir occasionally to ensure it cooks evenly.

After the zucchini is perfectly golden, add in the corn kernels and allow them to cook together for an additional 2 minutes. Stir frequently, watching for a gentle sizzling sound as the corn warms.

Return the sautéed sausage, bell pepper, and onion mix into the skillet with the zucchini and corn. Stir everything together. If you enjoy heat, sprinkle in red pepper flakes at this point, then season with kosher salt and black pepper to taste.

Lastly, sprinkle the dried or fresh basil over the mixture, giving it a gentle stir. Let everything cook together for another 1-2 minutes to ensure it's heated through. Serve hot and enjoy!
