01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper. Place the peach halves cut side up on the baking sheet. Roast for 15–18 minutes until softened and caramelized. Let cool slightly, then slice.
02 - Bring 2 cups of water to a boil in a medium saucepan. Add the quinoa, reduce heat to low, cover, and simmer for 15 minutes or until the water is absorbed. Remove from heat and fluff with a fork. Let cool to room temperature.
03 - In a small bowl, whisk together olive oil, lime juice, honey, Dijon mustard, salt, and pepper until well combined.
04 - In a large bowl, combine cooled quinoa, arugula, cucumber, red onion, and mint. Drizzle with the vinaigrette and toss gently to combine. Arrange the roasted peach slices on top. Sprinkle with feta cheese and toasted almonds.
05 - Serve immediately, or refrigerate for up to 2 hours before serving for a chilled salad.
