This food cart, Sideshow Eatery, started out with mainly side dishes 6 weeks ago, but recently added sandwiches, and a photo from Food Cart Portland of their pork belly sandwich successfully tempted me to try it for lunch after a dentist visit downtown. They are open until 11-6pm so if you hurry you could grab this after work as well- these hours are good M-Sat, they are open 11-4 on Sun so their sign says (so they are open on the weekends!). Besides the pork belly sandwich, they also offer a Caprice vegetarian sandwich of mozzarella, heirloom tomatoes and basil mayo, and a PBJ sandiwch which uses peach jam and homemade peanut butter.
Pork belly sandwich is a quickly seared pork belly nestled atop arugula for a bit of bite, sriracha mayo (spicy and creamy, but more towards the kick end of the spectrum), and pickled red plums for a bit of sourness, all in a toasted Pearl Bakery baguette.
Poutine was the side I chose, though you can also get regular pommes frites (twice fried yukon gold potatoes… yes, fries.) and then enjoy them with your choice of handcrafted sauces varying from curry ketchup to garlic mayo and sriracha mayo or Japanese mayo. My poutine was plain, but you can also add extra cheese and gravy, chopped onion, or bacon. If your arteries are still flowing, consider that Sideshow also offers fluffy sugar coated beignets, those New Orleans style powdered square doughnut covered in powdered sugar, and you can even order chicory coffee to go with.
