Collard greens can be sandy, so to clean them, submerge them in water to loosen any grit, then wash and dry. This technique of blanching the collard greens in boiling water, then sautéing them takes away any bitterness.
1. Bring large pot of water to a boil. Add collard greens, and simmer 5 minutes. Drain.
2. Heat olive oil in same pot over medium heat. Add garlic, and sauté 1 to 2 minutes, or until golden brown and fragrant. Add greens, and sauté 5 minutes, or until tender. Season with salt and pepper, and serve warm.
