Bring to a boil all ingredients except the oats. (I use a 3 quart pot, why do you ask?) Turn heat to low and stir in 4 1/2 cups rolled oats. Cook for about 5-10 minutes until the water is absorbed. Don't overcook. Not a major warning here, but if it is too soupy, add some oats at about 5 minutes and cook for a few more minutes instead of cooking it longer. I haven't had to add any oats the last 5 or 10 times I've made this). Fill a rectangular non-stick baking pan with the mixture (we are making square burgers here, a lot easier than forming little circles). Your pan should be anywhere from 9x18 or larger. Depends upon how thick you want them. I like them about 1/2 of an inch thick. I wouln't make them any thinner, because they'll be tough and will dry out . (Note: I wrote everything down but the pan size when I made these the last time, and I usually fill one or two of whatever is clean. You may need two pans. Sorry.) Total cooking time is 45 minutes. Bake at 350 for 25 minutes. Then use a utensil that won't scratch your pan to cut the giant burger into little burgers, and flip them. Cook another 20 minutes. Taste great hot or cold.
