So, cut the meat into thin strips, fry with salt and spices.
Eggs sliced not chopped, medium dice.
Tomatoes and cucumbers, cut as well, not very finely.
Lettuce to break it.
Meat, egg, cucumbers, tomatoes and salad dressed with mayonnaise, add salt to taste. Add the crackers before serving the salad, and mix everything again.
This salad can be dressed with olive oil, as for me, the taste is not worse.
