Step 1

In a heavy skillet over medium heat, melt the butter. Toast the pecans for a few minutes and then sprinkle with the sugar and salt. Cook one more minute. Watch carefully so they don't burn. Transfer the nuts to a sheet of parchment paper on the counter and allow them to cool.

Step 2

Place the torn lettuce in a salad bowl, top with cooled pecans, diced apples and feta. Dress the salad immediately before serving.
