Preheat the oven to 200 ° C top / bottom heat and brush a baking dish with a little olive oil.
Work the turkey meat into thin slices with a meat tenderizer and season with salt and pepper. Cut the mozzarella and tomatoes into thin slices. Spread the pesto on one side of the meat with a spoon and top with tomato and mozzarella. Place two to three basil leaves on top and roll them up carefully. The roulades may need to be fixed with a few toothpicks so that they don`t fall apart.
Put the olive oil in a coated pan and fry the roulades on all sides. Then put the roulades in the baking dish and season with a little oregano. Put everything in the oven for 15 minutes.
