Here's another one that had me going huh? when I first saw it a few years ago.
... I'm glad I tried it and always look forward to it during watermelon season.
Watermelon Slaw
4 - 2" watermelon wedges, rind removed
4" piece seedless English cucumber, peeled
1 large apple, cored
1 tbsp. + 1 tsp. lemon juice
sugar or sugar substitute to taste
Mix lemon juice and sugar in glass bowl.
Cut watermelon, apple, and cucumber into julien strips.
Add to bowl and toss all lightly.
Refrigerate at least 1/2 hour before serving.
* I prefer a bowl with a secure lid, and then shake it all periodically, to be sure all get well marinated.
* Some feta sprinkled on top, can be a good protein addition providing a taste/texture contrast.
* Good as a main course side, although I like it as an anytime of day treat!!
