In a 12-inch skillet heat oil and garlic over low heat for 1 minute. Brush some of the warm garlic oil over bread slices; set bread aside.
Stir vinegar, brown sugar, and the 1 teaspoon paprika into the remaining garlic oil in skillet. Stir over medium heat until sugar dissolves. Stir in greens; cook for 1 minute or until lightly wilted.
To serve, use tongs to transfer greens to serving plates. Top greens with eggs and cheese. Sprinkle with tarragon. Drizzle any remaining dressing from skillet over salads. Serve with toasts and, if desired, sprinkle with additional paprika, salt, and pepper.
