In a large bowl, combine ground turkey, salt and pepper.
When the salt and pepper have been well blended into the meat, divide it into 4 even sections.
Shape each section into a patty.
Pour the olive oil into a skillet and heat to medium-high heat.
Cook the burgers for about 7 to 8 minutes on each side.
While the burgers are frying, mix together the chicken stock, shallot, Dijon, capers, garlic, and thyme in a bowl.
About 2 or 3 minutes before you finish frying the burgers, pour the chicken stock mixture into the skillet. Turn the patties at least once so they can get a good coating of the mixture.
Prepare the buns with a choice of greens and add the cooked patties upon serving.
