Spread the remaining mayo on the inner side of each slice of toasted bread.
Add a generous layer of heirloom tomato slices.
If desired, sprinkle with:
- A drizzle of olive oil or balsamic glaze
- Fresh herbs like basil or chives
- Crushed garlic for a kick
Top with the second bread slice, mayo side down.

Slice diagonally for that classic café feel.
Serve immediately while the bread is still warm and crispy.
Tip: Pair with a crisp iced tea or lemonade for the ultimate summer combo. 🍋🧊
