Preheat the oven to 350°F.
Place your walnuts and buns in the oven on lined or sprayed baking sheet and bake them for 10 minutes. Then, set them aside.
In a pan, over medium heat, add your minced garlic and drizzle it with olive oil. Cook until it’s translucent.
Add the mushrooms, onions, and Italian seasoning and continue to cook the mixture for 5-7 minutes.
Rinse and drain beans.
Lightly smash beans with your hand. Mash most of them leaving only a few solid beans.
In a large bowl combine your beans, panko, walnuts, mushroom/onion mixture, red pepper flakes, basil, and salt/pepper. Press the mixture into balls and set them aside.
In the same skillet, over medium heat, add a drizzle of olive oil and cook each ball for 5-7 minutes. Make sure to rotate for an even cook.
