Final answer:
When building a panini, tomatoes can be overlapped or placed side by side depending on personal preference and desired texture.
Step-by-step explanation:
When building a panini, the tomatoes can be overlapped or placed side by side, depending on personal preference and the desired texture. Overlapping the tomatoes can create a more cohesive and compact sandwich, whereas placing them side by side can provide a more visually appealing and evenly distributed tomato flavor.
It's important to note that regardless of how the tomatoes are arranged, they should be sliced thinly to ensure they are cooked through during the grilling process.
