First knead a dough from the ingredients for the tortilla breads. Divide the dough into 6 equal parts. Heat a frying pan over medium heat and roll each piece into a round shape. Fry the tortillas in the pan on both sides for 2 minutes. Cut them in half and form a cylinder from each half. Fasten the cylinders with a toothpick and fill them with the cream salad (you will prepare it by mixing all the ingredients for the cream salad together until they create a homogenous mixture.) Repeat the procedure with all the halves of the tortilla loaves. Arrange them in a pan lined with parchment paper and grate yellow cheese on them. Bake in a preheated oven at 180 degrees for about 15 minutes. Serve tomato sauce in the middle of the serving dish.
