Preheat your oven to 400°F (200°C). Line two large, rimmed baking sheets with parchment paper.
In a medium bowl, combine the thoroughly dried chickpeas and grapes. Drizzle with 1 tablespoon of olive oil, sea salt, and black pepper. Toss to coat and spread in a single layer on one of the prepared baking sheets.
In a separate small bowl, toss the raw almonds with the balsamic vinegar and smoked paprika until evenly coated. Spread them in a single layer on the second baking sheet.
Place both baking sheets in the oven. Roast the almonds for 8-10 minutes, until fragrant and toasted. Roast the grapes and chickpeas for 15-20 minutes, until the chickpeas are slightly crisp and the grapes are soft and just beginning to burst. Remove from the oven to cool slightly.
While the items are roasting, prepare the vinaigrette. In a small bowl or a jar with a lid, combine the ¼ cup of extra virgin olive oil, fresh lemon juice, Dijon mustard, minced garlic, and dried oregano. Whisk or shake vigorously until the dressing is smooth and emulsified.
To assemble the salad, place the fresh arugula in a large, wide salad bowl. Drizzle with about half of the vinaigrette and toss gently. Top the greens with the warm roasted grapes, chickpeas, and spiced almonds. Drizzle with the remaining vinaigrette and serve immediately.
