Place green beans in a small nonmetal bowl. Sprinkle with water. Micro-cook, covered, on 100% power for 5 to 6 minutes or just till tender. Let stand, covered, while preparing butter mixture. For butter mixture, in a custard cup micro-cook butter or margarine, uncovered, on 100% power for 30 to 45 seconds, or till melted. Stir in toasted almonds and lemon juice.
