Step 1

In a large skillet over medium-high heat, warm the oil. Add the vegetables and toss to coat. Season with salt and pepper to taste. Add 1 tablespoon of water to the skillet and cover with a lid for 2-3 minutes to partially steam the vegetables.

Step 2

Uncover and continue cooking, tossing constantly, for about 4-6 more minutes. You want the vegetables to turn bright green and stay fairly crisp while barely softening from the heat.

Step 3

Add the butter to the bottom of the skillet and toss quickly to coat the pieces. Remove from the heat and sprinkle with Parmesan before serving. Enjoy!
