Ingredients

2 cups Portobello mushrooms, cubed (smaller pieces); gills removed *see note about sauteing first.
2 cups cooked black beans, rinsed and divided
1 cup minced broccoli, fresh only
1/2 cup red onion, minced
3 XL eggs, beaten
1/2 cup plus 2 tablespoons Panko or Gluten Free Panko
1 tablespoon Montreal Steak Seasoning

Olive oil

Cuisine

Steps

In a large bowl add 1 cup of black beans and mash with a masher (chunks are OK).
Next, add in the mushrooms (preferred sauteed), the rest of the beans, broccoli, garlic, onion, Worcestershire and steak seasoning.
Mix just until coated.
Add in the eggs, cheese and bread crumbs and mix gently with a large spoon until the mixture is combined.
Set aside while you place a medium non-stick pan over medium heat and add in 2 tablespoon of oil.
Once the oil starts to shimmer (about a minute or two), using dampened hands (the mixture will stick to you if you don’t), scoop a 1/2 cup of mixture into the palm of your hand and gently shape into a burger all the while pressing together. The mixture should hold a burger shape. If it doesn’t add just a tablespoon more of bread crumbs.
Place in the oil and cook for 3-5 minutes per side or until golden brown and a crust has formed on each side.
Serve with hummus, guacamole or steak sauce.

I've made this recipe a few times. Recently I tried sautéing the mushrooms and when they were soften pushed them to one side of pan and added 1 can of the black beans and after 2 minutes smashed them. I then added the garlic, onion and seasoning and the broccoli which I had cooked in the microwave for 2 minutes and drained well and finally the other can of beans. I found cooking all ingredients together slightly for a few minutes including the seasoning made a great difference. I did cool b4 adding eggs and bread crumbs. I appreciate your recipe so much. Super delicious!! Thank you! Happy Holidays!!

Hello from Athens! I just bought some Portobellos and need to try this recipe. Can I sub the broccoli with something? Thanks in advance 😊🙏

These are so delicious! I didn't have broccoli so I used kale. I sautéed the mushrooms first to remove water, then I sautéed red onion and kale together to remove water, then continued recipe as written except replacing Worcestershire sauce with coconut aminos. Will definitely make these again and again!
