Prepare rice by cooking then cooling. Soak oatmeal in water. Once oatmeal has expanded, drain any excess water.

In a frying pan saute the mushrooms and onions until moisture has evaporated and slightly golden brown. Allow to cool

In a bowl, combine rice, flax mixture, oatmeal, sauteed mushrooms & onions, all seasonings, cheese and cornstarch. If your mixture is too chunky feel free to chop it in a food processor.

Chill mixture for about 15 minutes to allow for easier handling.

Preheat oven to 325ºF.

Scoop approximately 1/2 cup of the mixture and create a patty and place it on a cookie sheet lined with parchment.

Bake for 12 minutes on each side. Remove from heat and allow to cool.

Heat via bbq or frying pan and serve on a burger bun with all your favorite toppings!
