Toast the Bread: Lightly toast the slices of bread in a toaster or on a skillet until golden and crispy. Ensure the bread is still soft inside and has a nice crunch on the outside.
Spread Pesto (Optional): If you're using pesto, spread a thin layer on each slice of toasted bread. This adds extra flavor to the tartine.
Arrange the Tomato Slices: Layer the thin slices of ripe tomatoes evenly over the bread. Make sure the slices cover the bread fully, creating a colorful and fresh base for your tartine.
Season with Salt and Pepper: Sprinkle Maldon or fleur de sel over the tomatoes to bring out their natural sweetness. Add freshly ground black pepper and, for some heat, red pepper flakes if desired.
Drizzle Olive Oil: Drizzle a generous amount of extra virgin olive oil over the tomatoes and bread for a rich texture and enhanced flavor.
Serve: Serve the tartines immediately while the bread is still warm and crispy. Enjoy as a light lunch or appetizer!
