The vegan-based food outlet had a humble beginning.
"Tim and I built the trailer ourselves out of what we could afford which wasn't all that much and it got to a point where we couldn't keep up with demand," he said.
"We would do these events like the Vegan Food Fair where we sold 460 burgers in six hours - we couldn't keep up with demand - so we needed to upgrade our equipment.
"We couldn't afford to do it ourselves so we reached out and people were super generous. A lot of like-minded businesses collaborated and gave us shout-outs."
The on-the-move business was thought up in August last year by co-founder and brother Tim Burrows before operations begun in February.
"We spent the summer getting the trailer up and running and had a builder friend come and give us a hand. We had no idea what we were doing but sort of built it from scratch which took a bit longer than we had thought," Burrows said.
Burrows said a total of over $30,000 was needed to refurbish and re-purpose the mobile unit.
"We set the target [of $15,000] and we had to reach a target otherwise we wouldn't get anything. We budgeted $30,000 for the upgrade and thought we would put half in ourselves and half from everyone else."
Burrows said all the money had been spent on upgrading to a massive gas cooker and gas system, new fryers, new benches and purpose-built storage.
"It's a lot more sleek operation now, everything is purposed built for the space as opposed to just chucking things in to make them work."
When Burrows is not working as a solicitor, he can be found flipping burgers in various parts of the country on the weekends.
Despite working more than 80-hour weeks and juggling two professions, Burrows said it was rewarding: "If you want something to happen, you'll make it happen."
Public reaction to the meat-free business had been very positive, he said.
