How to Make It
Preheat oven to 350°.
Line a baking sheet with parchment paper; coat with cooking spray. Combine salt and egg white in a medium bowl, stirring with a whisk until frothy. Add sunflower seeds and next 5 ingredients (through chili powder); stir to coat. Spread mixture in an even layer on prepared baking sheet. Bake at 350° for 15 minutes, stirring once after 10 minutes. Cool granola completely.
Combine oil, vinegar, and honey in a small bowl, stirring with a whisk. Place about 1 cup melon on each of 8 small plates. Top each serving with 1 1/2 teaspoons vinegar mixture, 1 1/2 tablespoons granola, and 1 tablespoon basil.
