Preheat oven to 375 degrees Fahrenheit. Spread almonds on a rimmed baking sheet and toast until golden - about 5 minutes. Set aside. In a large, non-aluminum skillet, heat oil over medium high. Add collard greens which should still be slightly wet from washing. Add dates. Toss occasionally until collards are tender - about 6 to 8 minutes. Serve sprinkled with toasted almonds.
