Black Bean Tostada Burgers

So I didn't realize how old this magazine article was tell just now but it is from Shape, August 2008 and I just made it for the first time but it was so tasty and cheap I think this meal will set you back maybe $5-6. I always have a can of black beans in my cupboard anyways.

"Ingredients
For The Pico de Gallo
1 large beefsteak tomato, seeded
and chopped (about ¾ cup)
¼ cup finely chopped red onion
1 to 2 jalapeños, seeded and finely chopped (about ¼ cup)
1 tablespoon lime juice
1 teaspoon extra-virgin olive oil
2 tablespoons chopped fresh cilantro
Kosher salt and freshly ground black pepper to taste

For The Burgers
1 15.5-ounce can low-sodium black beans
Cooking spray
1/3 cup finely chopped red onion
3 cloves garlic, minced
¼ cup panko (Japanese bread crumbs), preferably whole-wheat
½ teaspoon ground cumin
½ teaspoon dried oregano
¼ teaspoon kosher salt
Freshly ground black pepper to taste
8 small (6-inch) corn tortillas
1 large California avocado, peeled and sliced

Directions
To make the pico de gallo, combine tomato, onion, jalapeños, lime juice, olive oil, cilantro, salt, and pepper in a medium bowl. Stir, cover, and set aside at room temperature for up to 30 minutes, or refrigerate for up to 3 hours to allow flavors to blend.

To make the burgers, rinse black beans in a colander and set aside. Meanwhile, coat a medium skillet with cooking spray and heat to mediumlow. Add red onion and cook, stirring occasionally, about 5 minutes, or until soft. Add garlic and cook, stirring constantly, 2 minutes more.

In a large bowl, combine black beans, onion mixture, panko, cumin, oregano, salt, and pepper. Mash, allowing some chunks to remain. Form bean mixture into four patties about 3 inches wide and half an inch thick.

Divide tortillas into two stacks of four and wrap each stack loosely with foil. Place burgers and tortilla packets on a lightly oiled grill and cook for 4 minutes. Flip burgers and packets and cook for 3 minutes more, or until burgers are lightly browned. To serve, arrange two tortillas on each of four plates. Top with a burger, salsa, and avocado slices and serve." (Shape, August 2008, p152)
