Add thyme and garlic, and cook 1 minute, stirring constantly. Add potatoes and 1/4 cup water; cover and cook over medium-low heat for 15 minutes or until potatoes are tender, stirring every 5 minutes. Stir in kale, spinach, salt, and pepper; cook, covered, 3 minutes or until greens wilt. Remove pan from heat; keep warm.
Add water to a large skillet, filling two-thirds full, and bring to a boil. Reduce heat; simmer. Add vinegar.
