Preheat a broiler, oven or grill to medium-high heat.
Toast the bread until lightly golden brown on both sides-the bread should be crisp but still tender on the inside, not brittle. Remove and drizzle with extra-virgin olive oil and season with salt.
Combine the tomatoes, olive oil, vinegar, honey and oregano in a medium bowl and season with salt and pepper. Gently toss in the queso fresco. Let the relish sit at room temperature for at least 15 minutes before serving. Top the bread with the relish and serve.
