Preheat your oven to 350°F (175°C). Spread the pecans in a single layer on a baking sheet and toast them in the oven for about 10 minutes or until fragrant and golden brown.

In a small saucepan, combine the freshly squeezed orange juice, white sugar, apple pie spice, and lemon zest. Whisk ingredients over medium heat for 3-4 minutes until sugar dissolves, then strain the dressing into a bowl and let it cool.

Core both the green and red apples, then slice them into bite-sized pieces. Toss the apple pieces in lemon juice to prevent browning.

Peel the oranges and carefully cut them into segments, removing any seeds. Set the orange segments aside.

In a large bowl, combine sliced apples, dried cranberries, toasted pecans, grapes, and orange segments. Gently mix together.

Drizzle the cooled dressing over the fruit mixture and toss gently to combine. Serve immediately.
