Really tasty veggie burger

So I'd never actually made a veggie burger from scratch before. As a young vegetarian, I was introduced to Morningstar Farms veggie burgers by my aunt. They served me well for many years, until Gardenburgers came to Costco. Before that I could only get them at restaurants, but they were my favorite for a long time. I moved on briefly to Boca to increase my protein, but they were really just too heavy for me & don't actually taste very good. The last few years my husband have enjoyed the Morningstar Prime Grillers, which have a higher fat content and are a reasonable substitute for hamburger for omni-husband. But we're trying to move away from processed foods, as well as creatively incorporate more of our CSA haul every week.
One day I was watching the good old food network and Guy Fieri had his mom and sister on the show, and they were making veggie burgers. It seemed like there was a million ingredients, but the result sure looked tasty. I promptly forgot I ever knew they existed. Fast forward a couple years and I found the recipe during a random search. The recipe was accompanied by a 5 star review. (Granted the 89 reviews were bolstered by a ton of duplicate entries, but I went for it.)

Morgan's Veggie Patties

My only change: mash half the beans to help the patties stick together.
Garnish with red onion, horseradish mayo, avocado, lettuce and tomato. How can you go wrong?
