Stuffed Tomatoes  (Jitomates Rellenos) Ingredients:    * 6 ripe, firm tomatoes    * 1 can of tuna    * 1/2 cup of peas    * 3 stalks of celery, cleaned and chopped up    * 1/2 cup of mayonaise    * 1 pinch of baking soda    * salt and pepper Procedure: 1. Cook the peas in a little water with a pinch of baking soda. 2. Submerge the tomatoes in boiling water a few seconds to peel them more easily. Cut off the very tops of the tomatoes; hollow out a space inside the tomatoes carefully so they don't break. 3. Mix together the tuna, peas, celery and mayonaise. Fill the tomatoes with this mix. Serve on lettuce leaves and garnish with parsley. (Tomatoes may also be filled with potato salad, sardines, vegetables and even rice.)
