For the Belugaline Salad with Chicken and Tomato, cut the chicken into bite-sized pieces and brown well in a non-stick pan with a few drops of oil.
When the meat is cooked, set aside and let cool. Strain the lentils well and put them in a salad bowl. Wash and chop the tomatoes and add them to the lentils.
Now add the finished chicken to the bowl as well. Season everything with oil, vinegar, salt, pepper, mustard and sugar. Mix well and season or season to taste if necessary. Serve the salad.
