This easy, high-protein meal comes together quickly following an after-work workout. If you exercise at midday, save leftovers for lunch.
Serves 4 (serving size: 3 ounces tuna and about 1 cup bean mixture)
1. Cook green beans in boiling water 4 minutes or until crisp-tender. Drain and rinse with cold water; drain well.
2. Combine oil, next 6 ingredients, and 1/4 teaspoon salt in a bowl; stir with a whisk. Stir in beans, chickpeas, and tomatoes; toss. Sprinkle with walnuts, cheese, and olives.
3. Sprinkle tuna with remaining 1/4 teaspoon salt and pepper. Heat a grill pan over medium-high heat. Coat pan with cooking spray. Add tuna to pan; cook 3 minutes on each side or until desired degree of doneness. Divide bean mixture evenly among 4 plates; top with sliced tuna.
