Get a small baking dish and place ½ the basil in the bottom where you intend to place the chicken breast. Then lay the chicken breast on top of the leaves. Drizzle with a little olive oil, season with salt and pepper. Place the remaining basil leaves on the top pressing down to stick them. Drizzle again with a little extra olive oil.
Place in the oven and cook for 20 minutes turning half way. Allow to rest for 5 minutes before thinly slicing.
To make the croutons cut the baguette into 1 inch chunks and layout on a baking tray. Sprinkle over the crushed garlic and scatter over the diced butter. Drizzle with a little extra olive oil and season with salt. Bake in the oven for 15 minutes stirring at 10 minutes and then checking to see if they are lightly golden by 15.
Plate up your salad by arranging lettuce leaves on two plates, fan out the chicken slices, scatter a couple of croutons and drizzle with home made mayonnaise.
