How to Make It
Stir together cream cheese, cucumbers, red onion, dill, mint, lemon juice, vinegar, salt, and pepper in a medium bowl until well combined.
Spread about 1/4 cup of the cucumber mixture onto each slice of the toasted bread. Top each with 2 to 3 tomato slices, and drizzle each with 1 teaspoon olive oil. Sprinkle tomatoes with chives, salt, and pepper. Serve immediately.
