Just a note to say that chicken burgers are also good made with:
1 lb ground chicken
minced onion (1/4 onion)
minced shiitakes (4, rehydrated in a bit of hot water and some teriyaki sauce)
tbsp of korean spicy soup paste
the rest of the mushroom hydrating liquid (there was as little as i could get away with)
and then sprinkled with a little salt once they’re in the pan.
I made li’l mini-burgers, inspired by Just Bento, and they do seem to make it a little easier to eat smaller amounts of food. I had them with a scrap of leftover white rice and a pile of sauteed chard last night for dinner, and they was yummy.
