1Rinse and drain the black beans. Add to a mixing bowl.

2Mash into paste using a fork or your hands (wear a food-grade gloves).

3Rince and drain canned mushrooms. Finely chop them and add to the beans.

4Add oat flour (or ground oats), ground flax seeds, defrosted kale, tomato paste, syrup, garlic powder, onion powder, and salt to a mixing bowl.

5Mash and mix using a fork, an immersion blender, or your hands (wear food-grade gloves) until well combined.

6Preheat a large frying pan, preferably cast iron, over medium heat (induction #5). Brush or spray with oil. Divide the mixture into eight portions.

Tip: Transfer the mixture onto a piece of baking paper, then divide it into eight portions and shape each into a patty - this will make the process easier.

Place as many patties as will fit in the pan. Cover with a lid and cook for 3-4 minutes.

7Flip the patties and cook uncovered for another 3 minutes. Repeat with the remaining mixture.

8Meanwhile, prepare the avocado mash. Remove the pit and peel the avocado. Add avocado flesh, salt, and vinegar to a small mixing bowl.

9Mash until well combined.

10Transfer the patties to a serving plate and serve with the mashed avocado on the side.
