My husband and I LOVED these turkey burgers. I accidentally grabbed the bottle of Worcestershire sauce instead of soy and realized my mistake after I added it. I thought this would ruin it, but I put in a couple of splashes of soy sauce and the burgers ended up coming out super moist and savory.
I also added about 3 times as much sweet chili sauce to the mayo, but we like spicy foods. I also added some thinly sliced green onions to the mayo which freshened everything up a little bit.
