Ingredients

  • 5 cups roughly chopped mushrooms
  • 3 tbsp butter or olive oil
  • 2 large red onions
  • 3 cloves minced garlic
  • 1 tbsp fresh thyme or 1 to 2 tsp dry thyme
  • 1 cup ground oatmeal grind in food processor or you can use quick oats instead
  • 1 1/2 cups cooked brown rice
  • 1/2 cup brown rice flour plus a little more for dusting the patties before frying
  • 1 cup roughly mashed chickpeas
  • 1 tsp freshly ground nutmeg
  • 1/2 tsp freshly ground black pepper
  • 1/2 tsp kosher salt
  • 4 tbsp soy sauce
  • 1 tsp crushed chili paste or hot sauce or a pinch of chili flakes (more or less to taste)

For the Honey Dijon Mayo just mix together:

  • 3/4 cup plain mayonnaise
  • 2 tbsp whole grain Dijon mustard
  • 1 to 2 tbsp honey to taste

Instructions

  1. Saute the mushrooms in the butter until the mushrooms are well browned and have shrunken down considerably. Remove from the pan and set aside.
  2. Saute the onions and garlic together until fully softened.
  3. Add the onions and garlic to the food processor along with all of the other ingredients listed for the burger patties EXCEPT the mushrooms.
  4. Pulse together until well blended but not perfectly smooth. You want to leave some texture in the mix.
  5. You can quickly pulse in the mushrooms at this point but I prefer to mix them in by hand. This helps maintain their meaty texture.
  6. Chill the mixture for a couple of hours or even overnight before using.
  7. Form the mixture into 6 equal balls and roll the balls in brown rice flour, then form into burger patties.
  8. Cook in a lightly oiled cast iron pan over medium heat until well browned on each side. Serve on toasted buns with lettuce and tomato and Honey Dijon Mayo.
