01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - Rinse farro under cold running water. Combine farro, water or vegetable broth, and 1/2 teaspoon salt in a medium saucepan. Bring to a rolling boil over high heat, then reduce to a gentle simmer. Cover and cook for 25–30 minutes until grains are tender but still have a slight chew. Drain any remaining liquid and spread on a sheet pan to cool to room temperature.
03 - Toss the pitted, halved cherries with 1 tablespoon olive oil and 1/4 teaspoon salt until evenly coated. Arrange in a single layer on the prepared baking sheet. Roast for 10–12 minutes until the cherries are just softened and beginning to caramelize at the edges. Remove from the oven and let cool completely.
04 - In a small mixing bowl, whisk together 3 tablespoons olive oil, white wine vinegar, honey or maple syrup, Dijon mustard, and orange zest until fully emulsified. Season with salt and pepper to taste. Set aside.
05 - Using a sharp knife, cut the tops and bottoms off each orange to create a flat surface. Following the curve of the fruit, slice away the peel and white pith. Cut between the membranes to release individual segments. Set aside.
06 - In a large serving bowl, combine the cooled farro, roasted cherries, orange segments, sliced red onion, and torn basil leaves. Drizzle the dressing over the top and toss gently until all ingredients are evenly coated.
07 - Scatter toasted slivered almonds over the salad just before serving to maintain their crunch. Serve at room temperature or slightly chilled.
