The burger will feature a crumbed patty made from potato, peas, corn,
carrot, and onion, topped with cheese, lettuce, mayonnaise and pickles.

Unfortunately,
we won’t all have access to the burger yet. It is currently being
trialled at Mcdonald’s restaurants throughout South Australia. The trial
will determine whether it will be rolled out nationally.

“We
understand there’s a rising demand for vegetarian options, and we always
look to give our customers more of what they want,” shared Jo Feeney,
marketing director at McDonald’s Australia.

“We’re excited to be
trialling the McVeggie burger in South Australia so our customers can
give us feedback on it before we look to serve it up across the
country.”
