Cook quinoa according to package instructions to yield 1.5 cups. Quinoa typically takes about 15 to 20 minutes to cook.
While the quinoa is cooking, prepare the rest of the ingredients. In a large skillet over medium heat, warm a tablespoon of olive oil. Add the mushrooms and onion and cook for 5 to 7 minutes until the mushrooms shrink down and lose some of their moisture. Add the garlic and cook for a minute until fragrant. Pour the soy sauce into the skillet, stir to coat the veggies, and cook for 30 to 60 seconds before turning off the heat.
In a large mixing bowl, combine the cooked quinoa with the mushroom mixture. Stir in the beaten egg and navy beans. Finally, add the thyme, paprika, and salt, followed by the ground oats. Mix well. If the mixture appears too dry, add another beaten egg. If it appears too wet, add some more ground oats.
Use your hands to divide and form the mixture into 10 patties, about 2 inches in diameter each. Place them on a large plate or tray and cover tightly with plastic wrap. Put them in the refrigerator to chill for at least 30 minutes.
Warm another tablespoon of olive oil in a large skillet. Place the chilled burgers in the skillet and cook for 4 to 5 minutes on each side until lightly browned.
Serve on burger buns with sauce and toppings of choice or on top of a salad. Enjoy!
