Slice peeled oranges into equal pieces and arrange on a platter.

In a small saucepan, bring sugar, water, and vanilla extract to a boil over medium-low, stirring constantly. Simmer 5 minutes, then let cool.

Sprinkle orange slices with almonds and coconut, then drizzle with the cooled syrup. (If you have extra syrup, save for another use--I'm sure it would taste great in coffee!)
