Heat olive oil in a large skillet over medium-high heat. Add shallot and garlic and cook, stirring constantly, until fragrant (about 1 minute). Add cherry tomatoes, season with salt and pepper, and cook until the tomatoes have softened slightly, about 2 minutes. Remove from heat and stir in the chopped basil. Pour the tomato mixture evenly over the bread cubes in the baking dish. Sprinkle 1 1/2 cups of Romano cheese over the top, ensuring even distribution. Gently toss to combine. (10 minutes)
