To make lemon peel strips, use a vegetable peeler and peel top to bottom, capturing yellow only on a lemon. Repeat. Pour vinegar and water in saucepan. Add sugar, salt, lemon peel and bring to a boil. Stir to dissolve sugar and salt. Remove from heat and cool for at least 20 minutes. Poke tomatoes through, top to bottom with a very sharp, very thin knife. Poke again at a 90 degree angle. Toss with remaining ingredients and add cooled vinegar solution. Let stand at room temperature for 2 to 8 hours; then refrigerate.
