Preheat the oven to 400°F (200°C), slice the baguette into ½ inch pieces, drizzle with olive oil, and bake for 5-7 minutes until golden brown.

In a skillet, heat olive oil over medium heat, add diced tomatoes, and sauté for 2-3 minutes until softened.

Whisk together balsamic vinaigrette, honey, mustard, minced garlic, salt, and pepper, then drizzle in olive oil while whisking until smooth.

Combine cooked tomatoes with the vinaigrette and stir gently to mix.

Spoon tomato mixture onto the crostinis and serve warm for the best experience.
