Place cubed baguette on a sheet pan. Drizzle with olive oil and sprinkle a pinch of kosher salt over the bread. Using your hands, toss to coat. Bake for 10-15 minutes or until bread is toasted and golden brown on the edges.
Layer the toasted baguette, diced tomatoes, Persian cucumbers, feta cheese, and red onion on a serving platter. Drizzle with basil vinaigrette, garnish with fresh mint and basil leave and serve.
Basil Vinaigrette
While the bread is toasting, prepare the vinaigrette. Place basil, mint, garlic, shallot, olive oil, lemon juice, red wine vinegar, kosher salt, and black pepper in a food processor.
Blend until smooth. Taste and season with more salt and pepper if needed.
Notes
White balsamic vinegar can be used in place of red wine vinegar.
Leftover basil vinaigrette can be stored in an airtight container in the fridge for up to 5 days.
