- In a bowl, place the kale leaves and stir in the vegetable oil. Gently rub until the leaves are well coated with oil. Transfer the kale to a glass jar.
- In a small bowl, combine the boiling water, vinegar, honey, and salt until the salt dissolves completely. Pour over the kale and refrigerate for 2 hours.
- In another bowl, combine all the ingredients for the sauce. Reserve.
- Spread 1 tbsp of spicy sauce on each slice of bread.
- Garnish with pickled kale, carrot ribbons and tomato slices.
- Divide the pieces of grilled chicken and close the sandwiches.
Tip: Do you want to improve the nutritional value of your sandwich even more? Simply replace the mayonnaise with the same amount of plain Greek yogurt to prepare the spicy sauce. Not only will this sauce provide twice as much protein as mayonnaise, but it will also contain six times less fat!
