Charring is a great technique for coaxing extra flavor from vegetables without adding calories. Here, slender green beans stay crisp and fresh while taking on a hint of bitter and smoke for balance.
1. Preheat broiler to high with oven rack in top position.
2. Combine 1 1/2 teaspoons oil and beans on a rimmed baking sheet. Broil 5 minutes or until beans are lightly charred and tender, stirring occasionally.
3. Combine remaining 1 1/2 tablespoons oil, parsley, rind, and juice in a bowl. Stir in beans and nuts. Place bean mixture on a platter; top with feta, pepper, and salt.
