Step 1

Preheat oven at 350°F (175°C)

Step 2

Butterfly the chicken breast and pound it with a millet or a heavy object to even the surface. You want it to be approximately half an inch thick.

Step 3

Sprinkle with salt and pepper and cook it in a skillet in medium/high heat with a tablespoon of olive oil. Wait until one side has browned well (about 5-6 minutes) and then flip it. Cook the other side the same way.

Step 4

Put it in the oven to bake for additional 10 minutes and let it rest in a cutting board. Divide in two equal pieces.

Step 5

Lay some spinach leaves on one slice of bread. Put one piece of chicken on top and drizzle with some sauce.

Step 6

Lay some tomato slices on top, some basil leaves and drizzle again with some sauce.

Step 7

Top with another slice of bread.

Step 8

Repeat for the second sandwich.

Step 9

Eat.
