Before we jump into mixing, it’s crucial to have everything ready. Cook your black beans if you’re not using canned ones. Rinse and drain them thoroughly. Next, I like to use leftover brown rice as it binds the mixture beautifully. If you need a quick starch, just whip up some fresh rice—it won’t take long.

In a large mixing bowl, combine your black beans and, using a fork or a potato masher, gently mash them until they're mostly smooth but still have some texture. Think of it like mashing potatoes; you want it lumpy, not pureed.

To the mashed beans, add the cooled brown rice and finely chopped onions. Stir them together well. Here’s where the base of your burger starts to form. You want all those textures and flavors to meld.

Next, toss in your raw walnuts (or bread crumbs if you prefer). These provide a delightful crunch and a rich layer of flavor. After that, sprinkle in the panko bread crumbs. Mix it all together—you're looking for a consistency that holds together when shaped into patties.

Now, it’s time for the fun part—the spices! Add coconut sugar, chili powder, cumin, smoked paprika, salt, and pepper. I always remind myself that spices are the soul of the dish. Mix everything thoroughly to ensure the spices are evenly distributed.

Next, add the vegan BBQ sauce, soy sauce (if using), and fresh lime juice. This will enhance the moisture and give your patties that delicious, smoky, tangy flavor. Make sure you mix everything once more.

With clean hands (or a large ice cream scooper), form the mixture into patties. I generally make about six to eight patties, depending on your desired size.

Place the patties onto a plate or a lined baking sheet and cover them with plastic wrap. Let them chill in the refrigerator for at least 30 minutes. This step helps them firm up, so they’re grilling champions when it’s time to hit the flames.

Heat a grill or pan over medium heat. Lightly brush some avocado oil onto the grill grates or the skillet. Carefully place your patties on and cook for about 4-5 minutes on each side, or until they are golden brown. If you want those stunning grill marks, don't flip them too early!

Once beautifully grilled, serve your veggie burgers on whole-grain buns or lettuce wraps. Top with your favorite veggies and sauces—and voilà! You've got one mouthwatering burger ready to impress.
