Heat oven to 350°F. Using cutters, cut 4 shapes from each slice of bread. Place on cookie sheet; brush with 1 1/2 teaspoons oil. In small bowl, mix Italian seasoning and garlic salt; sprinkle over shapes. Bake about 8 minutes or until edges begin to brown. Cool completely, about 15 minutes.
Meanwhile, in blender, place basil leaves, vinegar, sugar and salt. Cover; blend on high speed. Scrape sides. Add 1/4 cup oil; blend until smooth, stopping once or twice to scrape sides.
In large bowl, toss greens, cucumber, tomatoes and carrots with dressing. Top with feta cheese and croutons.
