I slow cooked the wings, legs, thighs and back meat with a bit of chicken broth until it would fall from the bones, chopped it up pretty fine and made enchiladas with it. Worked out great. The tendons pulled right out. I would think the same would work great for tacos and chili. You could cook all the meat at once,chop it up and freeze it in the quantities you want for several taco, enchilada, chili meals! Good luck! As for burger, i would think you will need to add something to brown it in. We make goose sausage every year and add pork, but i think some olive oil would work to preserve the turkey flavor and keep it healthier.
