I had Rojak (lower right) for the first time, as part of a quick lunch:

Rojak is Malay for “mixture”, and I hear it varies vendor to vendor, but the one I had was a collection of fried (but still cool and crisp) fruit and crisp watery vegetables (including something that reminded me of jicama), friend dough, and an interesting spicy and sweet sauce that I think was peanuts, shrimp paste, chili, and a little sugar. I liked that it was a bit less in the sweet direction than many sweet and sour sauces. Refreshing, and a good side dish / appetizer.
