Heat oven to 375 F or start grill. Bake or grill chicken breasts for about 10 minutes on each side until interior temperature is 165 F. Remove, cool and cube chicken.
In a blender, puree chipotle peppers with white wine vinegar and mayonnaise. Place all ingredients except spinach and tortillas in a bowl and mix thoroughly.
Place 2 ounces spinach and half the chicken mixture in each tortilla and wrap. Cut each wrap in half to serve.
