In a large mixing bowl, combine ground turkey, black beans, corn, red bell pepper, jalapeño, cumin, chili powder, smoked paprika, garlic powder, cayenne pepper, salt, and pepper.
If the mixture is too loose, add breadcrumbs to help bind the ingredients together. Mix thoroughly until all ingredients are evenly distributed.
Divide the mixture into four equal portions and shape them into burger patties. Ensure they are compact so they don’t fall apart on the grill.
Preheat a grill or grill pan over medium-high heat. Lightly brush the grill grate with olive oil to prevent sticking.
Place the burger patties on the grill and cook for about 5-6 minutes on each side, or until they reach an internal temperature of 165°F (74°C) and have nice grill marks.
During the last few minutes of cooking, place the whole wheat buns on the grill to toast lightly.
Once cooked, remove the patties and buns from the grill. Assemble your burger by placing a patty on a bun, followed by avocado slices, lettuce, and a generous spoonful of salsa.
Top with the other half of the bun and serve immediately with your favorite side.
Notes
Adjust cayenne pepper to taste for desired spiciness.
