Sprinkle 1/2 teaspoon pepper over beef; rub beef with garlic. Coat a large nonstick skillet with cooking spray; place over medium-high heat until hot. Add beef; cook 2 minutes or until browned, turning occasionally. Cook over medium-low heat 6 minutes or until desired degree of doneness, turning after 3 minutes. Remove from skillet; let stand 5 minutes. Cut into 1/4-inch-thick slices; set aside.
Combine strawberries and next 4 ingredients (strawberries through ginger) in a blender; process until smooth. Set aside.
Combine noodles, oil, salt, and 1/8 teaspoon pepper; toss gently to coat. Spoon 1 cup noodle mixture onto each of 2 plates; top each with 1 cup spinach. Arrange beef slices evenly over spinach; spoon 1/3 cup strawberry dressing over each salad. Sprinkle with sesame seeds.
