Veggie Fiesta Burgers with Cilantro Lime Mayo

These Veggie Fiesta Burgers with Cilantro Lime Mayo can get a little messy (like all good burgers should), so eating outside in nice weather is definitely recommended for easy clean-up!











15-oz. can black beans, drained and rinsed

1 Tbsp. avocado oil

1/2 red bell pepper, diced

1/2 yellow onion, diced

3 cloves garlic, minced

1/2 cup frozen corn kernels

1/2 cup panko bread crumbs

1 egg

1 Tbsp. Worcestershire sauce

1 Tbsp. chili powder

2 tsp. ground cumin

1/2 tsp.dried oregano

1/2 tsp. kosher salt

For Cilantro Lime Mayo:

1 cup mayonnaise

1 cup cilantro leaves and stems, loosely packed

Juice of 1/2 lime

1 Tbsp. honey or agave  

1/2 tsp. kosher salt

For serving:

4 burger buns

Sliced cheddar or pepperjack cheese (optional)

Lettuce leaves

Sliced avocado


  1. Start by making the Cilantro Lime Mayo so that it has some time to sit in the fridge and allow the flavors to come together. Finely chop cilantro. Add chopped cilantro to a small mixing bowl with the mayonnaise, lime juice, agave and salt, and stir to combine. Place the bowl in the fridge while you make the burgers.
  2. Preheat oven to 375 degrees F. Line a small baking sheet with parchment paper, and set aside.
  3. In a small skillet on the stove, heat the avocado oil. Add the diced onion and bell pepper, and saute for 5 minutes, until just beginning to soften. Add minced garlic, and corn kernels, and saute another minute. Remove skillet from heat, and set aside to cool slightly.
  4. While the veggies cool a bit, in a large mixing bowl, place drained black beans. Mash black beans with a fork, leaving a few small pieces.
  5. To the mixing bowl with black beans, add the sautéed vegetables, bread crumbs, egg, Worcestershire sauce and spices. Mix well to combine.
  6. Divide the burger mixture into four equal portions. Use your hands to shape the mixture into burger patties (they will be fairly large/thick; you can make 5-6 smaller burgers, if you prefer), and place patties on a parchment-lined baking sheet.
  7. Bake burger patties at 375 degrees F for 20 minutes, flipping the burgers once halfway through.
  8. If you want to add cheese, top each burger with sliced cheese, and broil on high for several minutes, until the cheese melts.
  9. Serve burgers on buns, topped with Cilantro Lime Mayo and your favorite burger toppings (lettuce, onion, tomato, and/or sliced avocado).
