Ingredients

• 4 medium, cut into 1/2-inch cubes tomatoes
• 2 tbsp extra-virgin olive oil
• 1 small, finely diced red onion
• 2 cloves, minced garlic
• 1 tbsp, leaves only fresh thyme
• 1/2 tsp salt
• 1/4 tsp black pepper
• 4 slices, 1/2-inch thick baguette
• 2 tbsp extra-virgin olive oil
• 1/4 cup, thinly sliced fresh basil
• 1/4 cup, grated Pecorino Romano cheese

Instructions

1. Step 1: Preheat oven to 400°F (200°C). Toss 4 medium tomatoes (cut into 1/2-inch cubes) with 1 tbsp extra-virgin olive oil, 1/4 tsp salt, and 1/4 tsp black pepper on a baking sheet; roast for 20-25 minutes until tomatoes are softened and edges are slightly caramelized, stirring once at the 12-minute mark.
2. Step 2: Heat 1 tbsp olive oil in a small skillet over medium heat. Add 1/4 cup finely diced red onion and sauté for 5 minutes until translucent, then add 2 minced garlic cloves and 1 tbsp fresh thyme; cook for 2 minutes until fragrant and garlic is golden.
3. Step 3: Combine the roasted tomatoes with the onion mixture in a bowl, add 1/4 tsp salt and 1/4 tsp black pepper, and let cool for 10 minutes.
4. Step 4: Heat a skillet over medium heat. Brush 4 slices of baguette (1/2-inch thick) with 2 tbsp olive oil, then toast for 2-3 minutes per side until golden and crisp.
5. Step 5: Spread the tomato mixture evenly on each toasted baguette slice, then top with 1/4 cup fresh basil (thinly sliced) and 1/4 cup grated Pecorino Romano cheese.
