The image shows a pop-up with the options 'Grill', 'Peel', and 'Add'. However, the actual question below asks to identify what is NOT used in the recipe from a different set of options: dairy products, meat, and seeds. Based on a typical omelette recipe, dairy products (like milk or cheese) and meat (like ham or bacon) can be ingredients. Seeds are generally not used in an omelette. The cooking method 'Grill' is also a possibility, though frying is more common. 'Peel' and 'Add' are general actions. Since the question specifically asks what is NOT used in the recipe from the list: dairy products, meat, seeds, seeds are the least likely ingredient for a standard omelette.
Answer: seeds
