These burgers are so good, we have eaten them twice in the past week. Once with chevre on kaisers and once with old cheddar on ciabatta. I added chopped onion to the mix as well. Ground turkey is super cheap at my grocery store so I love this healthy, inexpensive dinner! 1/2 a pound of turkey makes 4 burgers. I even keep an extra burger back for the next day's lunch and it is still juicy after reheating in the microwave.
A tip I read about ground turkey is not to treat it like ground beef and mix lightly - you want to pack it as tightly as possible into patties.
