Meatless Monday: Spicy Fricken Sandwich at Substance Diner

Meatless Monday: Spicy Fricken Sandwich at Substance Diner

May 10, 20211 min read

By popular request, Tucson Foodie has started a series of vegan meals on Mondays. Look out for our meat-free meal every so often on Monday.


If you’ve been down to MotoSonora Brewing Company in the past few months, you’ll notice a vintage trailer parked in the front parking lot — decked out in neon lights, shiny chrome, and old-school vibes.

What’s happening on the inside of the mobile diner is where the real treasure is, though. Substance Diner has created a vegan chicken sandwich that even meat-lovers can’t get enough of.

It’s called the Spicy Fricken Sandwich and, if you haven’t already, you’ve got to bite into its crunchy goodness sooner rather than later.

Between the sesame seed Kaiser roll bun is a scratch-made seitan cutlet, which is made of wheat gluten, and is then crusted in hot spices and deep-fried. On top of the savory cutlet is shredded lettuce, organic tomato, dill pickles, Frankenaise (spicy vegan mayo).

If you’re in the mood for an appetizer beforehand or while biting into the sandwich, consider ordering the Fried Pickles — arguably the best fried pickles in town.

You can find the food truck at MotoSonora Brewing Company from 3 – 9 p.m. on Monday – Thursday, 11 a.m. – 9 p.m. on Friday and Saturday, and 11 a.m. – 8 p.m. on Sunday.

Substance Diner is located at 1015 S. Park Ave. For more information, follow Substance Diner on Facebook or visit substancediner.com.

More about Matt

At a very young age, Matt Sterner was gifted with the artistic ability to masterfully roll a burrito to the highest of standards, but the wrapped medley of delicious innards wasn’t his first love. Matt’s first true love was a combination of reading, writing, and creating. He grew up reading comics, the ingredients list of his shampoo and conditioner bottles, choose-your-own-adventure books, and the Scrabble dictionary — something he found useful when challenging his grandmother to a game.

He attended college at New Mexico State University and graduated with a degree in Digital Filmmaking. One of his favorite classes was screenwriting because he became responsible for the story’s birth before it came to life on-screen. After school, Matt took on numerous positions at a local television station in Tucson. From dealing out stories about heartbreak to producing “fluffier” content for a lifestyle broadcast, he learned what it takes to adapt to the many emotions the world of media can stir. Since 2017, Matt has dabbled in the culinary world of Tucson as well as San Diego, California from time to time.

If you’re in the mood for strange stories, head over to his pride and joy, wonkytimes.com. And in case you’re curious — yes, after all of this time, he still manages to roll a killer burrito.

@Sonoranrestaurantweek runs from September 4 through 13, 2026, and it’s the perfect excuse to pair a day of Tucson sightseeing with a prix fixe meal. Since the Old Pueblo packs desert trails, historic missions, art districts, and a UNESCO City of Gastronomy designation into one metro area, visitors can easily build a full day around any interest and land near a Restaurant Week stop when it’s time to eat.

Swipe to see six itineraries built around Tucson’s core attractions, each paired with nearby restaurants participating in this year’s event. Menus and prices are subject to change, so it’s worth confirming details on the Sonoran Restaurant Week website before heading out.@Sonoranrestaurantweek runs from September 4 through 13, 2026, and it’s the perfect excuse to pair a day of Tucson sightseeing with a prix fixe meal.
