The Yumbo in Perth Western Australia was a massive size ham and cheese burger (or roll) made by Hungry Jacks (the Australian name for Burger King) it wasn't a sandwich. It was yum! Red Bull another local gourmet food outlet produced a competitor called the Hambo it wasn't as big but just as tasty! I used to work at Red Bull (this was actually 1978). To make one (because Hungry Jacks don't make them anymore and Red Bull no longer exists) slice a white roll in half, fold in lots of slices of shaved ham, with 2 slices of Krafty type cheese and microwave on normal for about 45 seconds. Just had one this morning and it was delicious!

The Yumbo was a great sandwich. When I was in High School (1976) We used to eat at Burger King a lot for lunch. We always ordered a Yumbo and orange drink. They were a little messy but oh, so good!!

I really miss those yumbos! Bring them back!! I get the ham & cheese at Arby's with 3 little pieces of ham or Hardee's had the best also until the Hardee's went away there are only about 6 of them in the state of MN. I want a yumbo every day! I'm going to contact the marketing people at BK!!!!
