Melon, Blueberry & Feta Salad with Ginger & Mint from Diana Henry's Simple. The recipe is available online here.
The recipe calls for 3 kinds of melon, which is a little excessive for my fridge, plus cucumber. I used pink watermelon, green Galia melon and orange Ambrosia melon and the colors do look lovely.
The dressing uses the vinegar from a jar of pickled ginger and the book photo looks like there's some of the pickled ginger itself in the salad so I added that too and it's delicious. How come I never thought to put pickled ginger in a salad?
