Sweet, salty, tangy, bitter—this flavorful salad has it all, as well as crispness from the toasted pecans and creaminess from the blue cheese. A mandoline creates perfectly thin slices of vegetables and fruit that combine beautifully with baby arugula. Dressing the shaved pear with lemon juice and salt and letting it stand for a few minutes while you prep the endive and radicchio not only prevents discoloration, it infuses the fruit with a tartness that balances its natural sugars.
