Blind bake pastry shells according to package directions. (If using Siljans crispy shell, omit this step) Let cool. Meanwhile, heat oil in frying pan over high heat. Add shallots and reduce heat to medium, medium high, cooking until shallots become transparent. (If you can’t hear the shallots frying, the heat is too low, if they are browning, the heat is too high). Add balsamic vinegar and continue cooking over medium heat until vinegar reduces and shallots are just moist, not wet. Remove from heat, add tomatoes and salt and pepper to taste. In the bottom of each shell, add a small dab of either Pesto or Kalamata Olive Tapenade. Cover with a spoonful of goat cheese, to almost the top of the tart sides. Top with the balsamic tomato-shallot mixture. Serve at room temperature or heat in a low oven to melt goat cheese and warm topping.
