We adapted this superb recipe from The Girls Who Dish: Top Women Chefs Cook Their Best (Whitecap). Chef Lesley Stowe of Lesley Stowe Fine Foods in Vancouver uses tomatoes with shrimp for this holiday nibble. At Chatelaine, we added chopped avocados for a more festive touch just before placing on the bread. This is also wonderful on salad greens.
Stir 1 peeled and diced avocado into the tomato mixture.
