Carefully slice the watermelon into one or more 1-inch round slabs.
In a large mixing bowl, add the softened cream cheese, lemon juice and vanilla. Using an electric mixer, beat until creamy.
Add the powdered sugar and beat just until smooth, being careful not to over-mix.
Using an icing or rubber spatula, spread a thick layer of cream cheese icing onto your watermelon 'crust'.
Top your watermelon pizza with the prepared fruit in a decorative pattern.
Finish by drizzling with honey, strawberry glaze, and mint leaves, if desired.
Slice, serve, and enjoy!
Notes
Make sure to prepare and serve your watermelon pizza immediately, as the juices from the fruit can start to pool on the cream cheese topping.
Patting the watermelon slice down with a paper towel before adding the cream cheese topping will make spreading easier.
The watermelon pizza should be served and consumed immediately. It can be refrigerated, but the water from the fruit may compromise the cream cheese mixture.
