Step 1

In a small bowl, mix ground flaxseed with 2 tbsp cold water until well combined and thick. Set aside for 10 minutes.

Step 2

Meanwhile, in a large bowl, mash black beans with potato masher until broken down.

Step 3

Add flaxseed, onion, garlic, beet, sweetcorn, coriander, thyme, paprika, flour and soy sauce to bowl, and mix well to combine. (If mixture feels too wet, add a little more flour.) Season with salt and pepper if needed.

Step 4

Divide black bean mixture into 4 balls, and shape into burger patties about ¾-inch thick.

Step 5

Heat 2 tbsp oil in a large frying pan on medium heat. Fry burgers for 4-5 minutes each side until browned. (If pan isn't big enough, cook burgers in two batches.)

Step 6

Serve immediately on burger buns with vegan mayo, lettuce leaves, tomato slices and any other favorite toppings. Enjoy!
