I am not a baseball fan, but I enjoy attending a live game once a year or so. The Nationals Stadium surprisingly has many vegan options, which makes it a big draw for vegans.
On this particular evening, I wanted something very light so I went to the South Capitol Sushi. You'd hope that a sushi place, even one in a baseball stadium, could make all of their own food. Unfortunately, that is not the case. I ordered the one thing that was vegan there -- the avocado rolls. When I got back to my seat, I read the ingredients on the package and was horrified. I thought I was ordering fresh avocado rolls. But, they had some peanut sauce in them that was made with all kinds of artificial ingredients including modified corn starch, caramel color, acetic acid, and red no. 40. Wow. I still ate them, but reluctantly so. And I was not happy. They were filled with more lettuce, carrots, and cucumber than they were with avocado so it was more like eating a plain lettuce wrap with some chili sauce.
Of the other options I saw at the stadium, there is the Field of Greens that offers [supposedly] vegan veggie dogs, burgers, and more. Other options include vegan chili at Hard Times Cafe and Ben's Chili Bowl. But, my favorite place, hands down is Shawafel, which has vegan cauliflower and falafel sandwiches that are so good. Next time, I'm going back to Shawafel.
