I think this is overpriced. The pieces of halloumi were pretty thin and not particularly soft and not at all 'squeaky'. I wasn't expecting too much, as it is Burger King and they're not known for their veggie options but was hoping it would have a bigger slice of halloumi. The sandwich was enjoyable but I don't think I'd bother not doubled up on the halloumi. Bun was soft and sweet plenty of lettuce and I didnt think there was too much mayo. Would choose this if I wanted an unhealthy cheese sandwich, not if i was specifically wanting halloumi. P.s. I've tagged this as vegetarian because the ingredients are, but it's worth noting that they fry the cheese in the same oil as chicken and fish... that's not something I'm too strict about for myself.
