Preheat oven to 375°F (190°C).

Sauté chopped mushrooms and minced garlic in olive oil over medium heat until golden brown (about 5 minutes). Let cool.

In a bowl, combine cooked quinoa, sautéed mushrooms, rolled oats, soy sauce, chopped herbs, salt, and pepper. Mix until well combined.

Form the mixture into patties (about half an inch thick).

Place patties on a parchment-lined baking sheet and bake for 25 minutes or until golden brown.
