What to eat at Chase Field: The Grand Slamwhich

At the beginning of this season, the Diamondbacks unveiled a list of new items available at concession stands around the stadium for the 2025 season. Some were more gimmicky than others, but there was none more gimmicky than the at the time named Grand Slamwich. Since then, according to the gentleman who assisted me at the park, theyve renamed it, but I dont remember. Something generic about 50/50 I think, probably because Dennys has a rather famous sandwich by the same name. What made it so gimmicky you ask? Well, its 20 submarine sandwich, half of which is chicken parmesan, the other half is a marinara meatball sub. Its big. It has a lot of bold flavors. It literally comes in a carrying case. It harkens back to the days of the D-bat Dog and other such monstrosities that have terrorized hungry fans for well over a decade now, but the question, of course, is it actually any good? Unlike previous offerings, this is clearly designed to share, and it explicitly says that on the menu board, recommending three people. In the past, I would have taken that as a challengea bit of parmesan cheese on top on a standard sub roll. Honestly, not much to write home about, but it wasnt terrible. The sauce was very acidic for my taste, but there wasnt so much of it either that it ruined the sandwich. Cheese was very stringy, which made for a good visual, but kind of messy. All in all Randy Johnson Jersey, not bad, but not great. Solid 5/10Next was the chicken parm half of the sandwich. This half of the sandwich was where I was most hesitant. A meatball sub is pretty easy to pull, but I dont go to a baseball game expecting decent pesto to be found anywhere. But thats exactly what was on that half of the sandwich. Fried chicken filets, marinara sauce, pesto, more alleged provolone, and dusted with parmesan cheese. About as far from ballpark food as you can shocked me, but this was actually really good. If the whole sandwich was this, I could probably eat it by myself. There was even less of the marinara, so less acidic, and the pesto did a great job of cutting the acidity even more. The chicken filets were the standard Tyson stuff the ballpark serves, but it was dressed up enough that it didnt really bother my snobby side all that much. 8/10 in all, it was a good sandwich for a lot of money. I enjoyed both halves of the sandwich at least somewhat, and it was a decent amount of food. Plus, the comments and stares it got as I was taking it back to our seats added a bit to the enjoyment of it. It was pricy though. If I didnt have someone willing to share it with me, it would be too much, and getting it requires everyone to agree on the same thing for lunch, not always possible. Its probably not an every trip meal. Im not sure if Ill ever get it again, frankly, but it was fun as a one off, and if you have one or two people willing to help you out, worth it for the novelty. Check it out at the Jefferson Street Deli behind section 121, but make sure to grab some napkins!
