Cook rice according to package directions, omitting salt and fat. Cool to room temperature; set aside.
Combine boiling water and sun-dried tomatoes in a bowl; let stand 30 minutes or until soft. Drain and cut into 1-inch pieces.
Heat 1 1/2 teaspoons oil in a large skillet over medium-high heat. Add spinach and garlic; sauté 3 minutes or until spinach wilts. Combine rice, tomatoes, spinach mixture, cheese, and next 5 ingredients (through chickpeas). Drizzle with remaining 1 tablespoon oil; toss gently to coat. Sprinkle with nuts; serve with lemon wedges, if desired.
