For perfect apple cubes: Stand the apple on your cutting board and cut down into four slabs; discard the core. Lay slabs, cut sides down, and cut into 1/2-inch slices, then crosswise into 1/2-inch cubes.
2 tablespoons low-fat mayonnaise
1 tablespoon lemon juice
2 small (Gala or Fuji) apples, cubed
1 cup seedless red grapes, halved
1/3 cup dried cranberries
1/4 cup coarsely chopped walnuts
1/4 cup thinly sliced celery (about 1 stalk)
8 Boston or Bibb lettuce leaves
How to Make It
Combine mayonnaise and lemon juice in a medium bowl. Add apples, grapes, and cranberries; mix well.
Add the walnuts and celery, and mix well. Serve it on a bed of 2 lettuce leaves. The salad can be refrigerated up to 2 hours before serving.
