Which item is not included in the omelette plato?

The item that is not included in the omelette plato is guacamole. The omelette plato typically consists of various accompaniments that complement the eggs, and guacamole, while a popular dish in many cuisines, is not listed among the standard side items for this particular offering.

In contrast, items like the arugula salad, crispy Spanish potatoes, and avocado salad are more traditional sides that enhance the flavors of the omelet itself and provide a balanced meal. These sides not only add texture and variety but also align with the typical components found in an omelette platter, which often seeks to provide a refreshing or hearty accompaniment to the main dish.
