1baguette loafthin sliced, brushed with butter and toasted
To a medium mixing bowl add the watermelon, avocado, feta, and lime juice. Gently stir everything together until well combined.
Lay out your toasts on a serving platter. Spoon a couple tablespoons of the watermelon mixture on top of each toast. (You can use as much or as little of the topping as you like, but the amount you use will cause the total number of bruschetta this recipe makes to vary.)
If you prefer, you can use bruschetta crackers or melba toasts for this appetizer.
