cup of boiling water to oats (just enough to cover them) and set aside as well.
In a medium pot sprayed with nonstick spray, cook vegetables for 5 minutes over medium-high heat, stirring occasionally.
Remove pot from heat and transfer veggies, with a slotted spoon, into a large bowl. Allow veggies to cool for several minutes. (If veggies have a lot of excess moisture, use a paper towel to soak it up.)
Add softened oats, ground Fiber One, soy sauce, salt, black pepper, garlic powder, and egg substitute to veggies. Stir thoroughly to combine. Make sure mixture is well blended.
Form mixture tightly into 5 balls and place them on a large plate. Cover and allow to cool and set in the fridge for several hours. (The longer they sit in the fridge, the better they'll keep their shape when you cook 'em.) Don't worry if they are a little bit watery—they'll firm up when cooking.
Using a spatula, flatten them into patties in a pan sprayed with nonstick spray and cook for about 5 minutes per side over medium heat (flip gently, so they keep their shape).
