Okara Burger, Avocado Fries (No Added Fat); New Soymilk Maker

I have been thinking for a while of buying a soymilk maker and just bought the SoyaPower G4 . (I also bought but didn't open their tofu making kit; I'll try it in the near future.)

It was a very light brown/off-white color with the consistency of thick oatmeal. I thought I'd make okara burgers for my daughter and me (and serve a non-soy burger to my soy-intolerant wife). I took the okara from a cup of soybeans, mixed in about 1/4 as much whole wheat pastry flour and the same amount of nutritional yeast, plus about the same amount of onion, chopped into 3/8" cubes, plus a pinch of salt, and made into two balls. I flattened them and put them in my air fryer. I baked at 350°F for six minutes to let the inside get cooked somewhat, then air fried for 5 more minutes also at 350°F. ...
