The escarole this time is going to be used to make a cocktail-type salad and fill some delicious avocados with salmon. This recipe can serve us both as a first course for a lunch and for a fresh and complete dinner since avocado is a filling fruit, even more so if we accompany it with fish and vegetables. With regard to fish, if salmon is not the children's favorite, we can substitute tuna, anchovies or shredded hake.
