Wash the turkey breast, dab dry and cut into 8 small medallions (0.5-1 cm thick). Cut mozzarella balls crosswise into 4 slices each. Wash, clean and cut the tomatoes into 4 slices.
Heat the oil in a pan with a lid. Season medallions with salt and pepper and fry them in the pan. Turn after about 2 minutes. Spread 1 tablespoon of pesto in the pan. Cover the meat with a slice of mozzarella and a slice of tomato.
Put the lid on the pan and fry for another 5-6 minutes. Wash the basil, dab dry and remove the leaves. Garnish medallions with basil leaves. Serve with pesto gravy. Roasted ciabatta bread tastes good with it.
