Rinse the Swiss chard under cold water. Remove tough stems and chop leaves into bite-sized pieces.

In a large skillet, heat olive oil over medium heat. Add minced garlic, sautéing until fragrant (about 30 seconds).

Add chopped Swiss chard to the skillet, stirring gently to coat with garlic. Cook for 3-5 minutes until wilted but still bright green.

Season with salt and pepper to taste; adjust as desired.

Transfer to a serving dish and serve immediately or drizzle with additional olive oil if desired.
